Bugs, Glitches and Exploits

This page is a list of all major bugs, glitches, and exploits in SkyBlock history. A more extensive list of current and old bugs can be found in this thread.

Definitions
'''Note that abusing bugs or exploits can result in a ban according to Hypixel's rules. We do not condone the usage of the bugs and exploits listed below. Please proceed cautiously.'''
 * A bug (also known as a glitch) is an error in the program that causes it to function improperly, and can result in unintended effects. (Some bugs don't give an advantage, and can merely be visual.) Examples include creating null blocks, warping through walls, and etc.
 * Exploits are loopholes that abuse the game mechanics in order to obtain unintended advantages. Examples include: AFK XP farming, anti-knockback, item/money duplication etc.

Hypixel's Exploit Prevention

 * To prevent exploits and hacking, Hypixel has a system called Watchdog that automatically bans players if they use blacklisted modifications.
 * To report other players, players can utilize the /wdr [player's name] command.
 * As of the 0.7.9 update, there is a CAPTCHA system designed to catch people using macros or etc. (This does not come up if the player is in an AFK pool or does not send inputs to break blocks.)

List of Bugs
These are a list of minor or major glitches. This list is not exhaustive, and more glitches will always crop up as new items or gameplay elements are added to the game.

End Shop/Jerry's Workshop Exploit
Status: 

As of Patch 0.7.7, all materials obtainable through minions were given an NPC buy limit of 640. However, a bug regarding the End Shop allows players to bypass the NPC limit. To bypass the cap, players can buy end stone or obsidian from the shop one at a time instead of right-clicking and buying in stacks. This also works in the shop in Jerry's Workshop run by Sherry.

Jungle Island/Dark Thicket Bug (Visual Bug)
Status: 

The labels for the Jungle Island and Dark Thicket portals are reversed. Instead of the Dark Thicket portal being labelled "Travel to the Dark Thicket", it reads "Travel to Jungle Island" instead, and vice versa. Both portals still lead to their correct locations, only the labeling is in error.

No Collection Crafting
Status: 

By using the Quick Crafting Area, players can craft pets without needing collection. For example, a Sheep Pet can be without having unlocked.

Horse-in-a-wall Exploit
Status: 

Players can glitch through one-block thick walls using a Horse Pet, Skeleton Horse Pet, or Pig Pet by summoning any of those pets inside the wall. This can be used to access the Howling Cave or Dragon's Nest (during a fight) in a way that is not normally possible. Instead of using the three previously mentioned pets, it is also possible to glitch through one-block ceilings or floors by summoning a rock pet, right-clicking it twice, and, lastly, summoning any other pet.

It is unsure whether or not this is regular Minecraft behavior or a Hypixel-only glitch.

Mushroom Desert Portal Bug
Status: 

Entering the Portal to the Mushroom Desert requires combat V and farming V when it should require only farming V.

Piggy Bank Withdrawal Bug
Status: 

Prior to December 3, the Piggy Bank was able to interact with the Banker remotely.

The function was originally meant to only be able to deposit coins, but after depositing the coins, the player would be able to open the original bank menu, allowing the player to withdraw coins without a cooldown.

The bug was patched on December 1, and the new function of the Piggy Bank on December 3. The Personal Bank is now used, and can be upgraded with Guy in the Hub Island.

Slime Hat Exploit
Status: 

There is an exploit involving the Slime Hat and a host of other ones in a bug called "armor stacking".

The Slime Hat Exploit is reproduced like so:
 * 1) Wear the Slime Hat on the head slot and then take it off then replace it with another head item (e.g. most of the Accessories or the Power Orbs)
 * 2) Switch back to a normal helmet and get anti-knockback without the slime hat equipped.

The bug was thought to be patched on January 9, 2020.

It was officially patched on March 4, 2020, along with multiple players complaining about the fix.

It had returned in another form:


 * 1) Warp another player into the player's current hub
 * 2) Wear slime hat
 * 3) Leave the lobby and put on a different helmet
 * 4) Get warped back to the first hub.

At some unknown time, the original patch was rolled back. The original exploit still works.

Private Island Bed Exploit
Status: 

This bug allowed players to farm thousands of candy points during the Spooky Festival on their Private Island. The exploit worked like this:

1) Turn the island biome into the Nether using a Biome Stick.

2) Fill a chest with Candy.

3) Place a bed next to the chest and right-click. It would explode.

4) Pick up the candy dropped from the chest.

Picking up the candy allowed players to receive candy points at an insane rate.

Hopper Glitches
Status: 

In early SkyBlock, items such as fairy souls, bait, coins on the ground, skeleton hat bones, and etc. Could be picked up with hoppers. These items are now unobtainable and those who have used this glitch before still hold the glitched items. Since they are no longer obtainable, they are extremely expensive.

Backpack Duplication
Status: 

The backpack duplication was an exploit that happened when wearing a Backpack (a head item) without a helmet currently in the slot. It would open the backpack content, allow the user to take out items, and take the backpack off the head without actually removing the item from the original backpack that was being held.

It involved the YouTuber Pigicial, whose rank was temporarily removed and was temporarily banned from SkyBlock for accidentally publicizing the bug.

Hypixel Staff had to manually go over 25,000 accounts to remove or rollback duplicated items. Only extreme cases were punished.

Vampire Mask AFK XP Exploit
Status: 

This exploit allowed players to harvest Combat XP in the Private Island by using Teleport Pads to change the user's direction, bypassing the anti-macro system that checks for head movement before awarding XP. The user would then equip a Vampire Mask near combat mobs by killing them using the mask's effect. This no longer works as the mask cannot be used on the Private Island.

Blue Whale Pet Invincibility Exploit
Status: 

On February 26, 2020, when the first Travelling Zoo event took place, Blue Whale Pet's ability gave 1  for every 0.3. Players wearing Mastiff Armor could effectively be invincible by having more than 90,000, equal to about 99.9% damage reduction. (With 20,000 HP, they would have about 18,000,000 Effective Health.)

Phoenix Pet Flight Glitch
Status: 

On February 21, 2020, just after the release of 0.7.6 Update, there was a glitch that allowed everyone who had a Phoenix Pet to fly freely in public islands. This was patched an hour after the update's initial release.

Session ID Exploit
Status: 

For five days in late-February 2020 to early March 2020, an exploit was discovered that allowed players to use session IDs to log on other accounts. This was exploited and players like IceBlades11 and TimeDeo's alt were hacked and lost millions of coins worth of items. The exploit wasn't unique to Hypixel, as players on the oldest anarchy server 2b2t were also affected.

This exploit used Minecraft Legacy Session IDs. Whenever a player joined a server, a unique session ID was generated that is sent to Mojang. Each player receives a unique session ID. By using an old system (known as the Legacy System), hackers could use any valid session ID to log on to any username. For example, a player can use the session ID for coolbean123, and the same player can then log on to any server as someone else. This allowed players to get hacked without any account details.

Thankfully, no staff on Hypixel were affected due to 2FA (two-factor authentication). However, popular streamers and YouTubers were majorly affected by the exploit. Mojang patched the exploit later.

Wearing non-wearable items (Minor Bug)
Status: A seemingly harmless bug exists where a player fills their slot bar and tries wearing a normally non-wearable item such as accessories or Summoning Eyes. Instead of the item being returned to the inventory, it will stay in the player's head.

The worn item will be returned once there is an empty slot in the player's inventory.

Lobby Crashes
Status: 

Hypixel has encountered massive problems regarding performance. Occasionally, lobbies will crash, causing rollbacks.

When the lobby crashes, the player's inventory, purse, and ender chest get rolled back to before the player joined the lobby. Some features that are not rolled back include the Bank, the Auction House, Slayers, and Pet XP. The bank withdrawal bug is a variant of this bug.

One of the most infamous ways to crash players was using the Banner, although it is heavily blacklisted, thus patching this method to crash.

Zero Poison DPS (Visual Bug)
Status:. If a player brews a potion of poison and dies because of it, the player will receive a death message. When the player respawns, the poison effect is removed, but the player still appears to take poison damage. Since the player does not have the effect anymore, the player receives 0 poison DPS.

Free Dark Auction
Status: 

When the Personal Bank was added, it could deposit and interact with the bank in Dark Auctions. Players could bid money on an item and deposit the money, as auctions did not take money away on bid. This resulted in winning free items, but it was quickly patched after lasting for one Dark Auction.

Trial of Fire Exploit
Status: 

A few days after the Park was added, a bug came where if a player can survive the first hit, they would take no damage in the Trial of Fire. Many players took this opportunity and maxed out their Campfire Badge. This can still be done by using the Wither Cloak Sword.

Automatic Combat XP Farming Exploit
Status:

Players could automatically farm Ghasts or mobs for combat XP in the Private Island by using an AFK pool and a way to deal damage, including but not limited to: Cactus Armor/Thorns, Blaze Armor, Vampire Mask, and Unstable Dragon Armor. This has been patched as of May 21, 2020.

Alpha Hypixel Network Bazaar and Auction House Glitch
Status:

On the Alpha Hypixel Network (AHN), the coins wouldn't be put in the AHN's Auction House and Bazaar, but instead on their main accounts in SkyBlock. This allowed the people who had access to the AHN to get trillions upon trillions of coins, drastically inflating the value of coins. This was quickly patched after the bug was discovered, and all coins transferred were deleted, reversing the damage done.

Flying in Hubs
Status: 

Flying in islands other than the player's own island was a glitch when mushroom soup time save was added. This happened because the timer also saved in hubs.

Quick Crafting Recipes Not Showing
Status:

When using the quick crafting menu, some items do not appear to be craftable despite having the materials needed.

SkyBlock Menu Clicking
Status:

When opening the SkyBlock Menu, sometimes the Menu clears all the items/selections for a split second and then goes back to normal. However, when this is happening, if the player tries to pick a category (ex. Your Skills), it shows that the player picks up the item; however, it does not open the category. Some people may not have this glitch, the reason being unknown.

Repeating Sound Effects (Minor Bug)
Status:

In mainly older versions of Minecraft, sound effects may repeat when doing certain actions (for example, taking materials out of a minion), although it does not do this every time a sound effect is played. This does not affect anything but the audio and its exact cause is unknown. Often occurs when closing GUIs such as the minion menu or your inventory.

Limited Auction House (Minor Bug)
Status: Occasionally when changing auction house settings, only one item from the auction house will be visible. This will appear in the top right corner of the available items on the auction house. As a workaround, exit out of the menu and then go back in. Although the auction house is bugged, players can still buy or bid on the visible item.

Dungeon starting bug
Status:

This bug occurs when a player dies as soon as a dungeon starts. When the player attempts to teleport to another player, the player will always teleport to themselves. However, the scoreboard will show that the player's health isn't zero.

Double Slab Bug
Status: 

When breaking a double slab with the Telekinesis enchantment, the player will receive one slab instead of two. Breaking the double slab with anything that does not have Telekinesis enchantment will not result in the bug.

Double Drops from Sea Emperor Exploit
Status: 

When the player uses a weapon that usually does area of effect damage, such as an Explosive Bow, Dreadlord Sword and Bonzo's Staff, the player can get double drops from Sea Emperors. This causes the Emperor to always drop 2 Emperor's Skulls, double fishing XP, and give the player increased chances of dropping a shredder or a Flying Fish Pet. This also works with Monster of the Deep, but since the Monster of the Deep doesn't drop anything valuable, it is less notable than the Sea Emperor.

Fuming Potato Books removes Anvil Uses
Status: 

When the player applies Fuming Potato Books to an item using a Reforge Anvil on the Private Island, the number of anvil uses on the item is reduced.

Double Death Inventory Wipe
Status:

One of the most deadly and devastating wipe glitches on the server,

If the player dies by taking an amount of equal to their, a vanilla Minecraft death screen would appear and if they press either buttons, "Respawn" or "Title Screen," their whole inventory, Ender Chest, and Pets are wiped. The only things safe from the bug are items on the player's own Island. This occurs mostly in Dungeons by Crushers dealing and Endstone Protectors performing a slam move also dealing. The only way for someone to avoid this was when greeted with the vanilla death screen, close by X-ing out, use Alt-F4, or use a mod that purposefully crashes your game to prevent any further loss of their profile. (It's not guaranteed that it will work.) This is patched as the Admins finally enabled the Keep Inventory Game Rule command to save players' inventories.

Dungeon Success Warp
Status:

If a dungeon is completed or failed and the party leader warps them into a dungeon, it will sometimes send the player into the same dungeon that they just completed/failed.

Deep Caverns Exploration
Status:

In the Deep Caverns, players can jump off the side to the left of the launch pad into the void to instantly "explore" all of the deep caverns floors. This tactic is commonly used by speedrunners to skip the Deep Caverns.

Dreadlord Sword Fishing Rod Exploit
Status:

This was a bug that causes the Dreadlord Sword's wither skulls to move fishing rod bobbers. This can be used to launch bobbers out of the water. This bug has plagued fishers ever since the item was added and is a popular choice by griefers when combined with the Frost Walker enchantment.

Great White Shark Crashing
Status:

When fishing up a Great White Shark in the new Fishing Festival, there is a chance that it will crash the lobby it was in. This happens if the sea creature is left alive for too long.

Weird Tuba placement glitch
Status:

The Weird Tuba placement glitch is a glitch where the Weird Tuba can be placed as a block. When placed, it is interactable with as a normal Hopper. If it the block is mined, it drops as a normal hopper, causing the weird tuba to be destroyed. The same bug also happens to The Cake.

Spirit Leaps counting as several secrets
Status:

If Spirit Leaps are picked up from Secret item drops individually, they will be counted as separate Secrets, allowing the player to gain 5 secrets from a single Spirit Leap drop. This also works with Inflatable Jerry drops.

Secret Bats Dying
Status:

When Secret bats in Dungeons die from causes other than player attacks (mob attacks, fire, etc.), it will not count towards the secret counter in the room, which renders it impossible to find all the secrets in said room.

Dungeon Ghost Mobs
Status:

Occasionally when entering rooms which had been cleared by another player, mobs will appear as "ghost" NPCs - their model showing, but unable to move, attack or take damage.

Bonemerang Stunning Thorn
Status:

Using a Bonemerang to attack Thorn causes it to be stunned in place. This does not damage Thorn. Upon recovering from the stun, Thorn will move extremely quickly around the arena, often glitching out.

Prevent Livid Clones from Spawning
Status:

Using the Leaping Sword or Silk-Edge Sword ability on Livid before the fight began would prevent the seven Livid Clones from spawning.

Mob Stun with Frozen Scythe and Spider Pet
Status:

Using a Frozen Scythe to attack mobs with a Rare or higher Spider Pet causes the mob to be frozen in place. The mob can still attack. This also works with other slowing abilities such as that of the Voodoo Doll.

3/1 Secret Room
Status:

In a certain room in The Catacombs, the secret display shows only 1 secret, but 3 secrets can be found.

Using Traps to Complete Ice Path Puzzle
Status:

In the Ice Path puzzle room in the Catacombs, players could push the silverfish against a placed Trap, allowing the player to easily complete the puzzle. As of the patch, pushing the silverfish against a Trap will cause the puzzle to be failed.

Three Weirdos Puzzle Answer Exploit
Status:

By clicking on each chest in the Three Weirdos puzzle room before talking to any NPC, the correct chest could be determined.

Save Inventory Bug
Status: 

By opening the Builder's Wand menu and then hitting the escape button to close out of it, the message "save inventory" would be displayed to everyone in the lobby. This caused a lot of people to spam public lobbies with the text causing everyone to be confused.

Dark Auction Exemption Bug
Status:

When the Dark Auction was first released, players would overbid an item to extreme amounts and at the last second leave; the 2nd place player would get the item. For example, for a Midas' Sword, players would bid like so:


 * Player A bids up to 50 million, and then player B bids 60 million.
 * Player A then bids 70 million, and player B bids 80 million.
 * Player A bids 100 million. Finally, player B bids 150 million.
 * At the last second, player B leaves and player A is stuck with a 100 million Midas' sword.

This was patched and now when the player leaves the Dark Auction, their bids will be saved. And if the top bidder leaves before the countdown and wins, their items will be delivered to Jerry.

Day and Night Saver Bug
Status:

The Day/Night Saver Bug was a bug only a tiny amount of people knew in the early weeks of SkyBlock. It involved placing a Day and Night Saver on 2 blocks, and the effects of both cancelled each other out. Afterwards, players could then mine the blocks underneath and they would turn into Null items. The type of block players would depend on what time it was set in. It was quickly patched after it was discovered.

(Most Likely Visual) Island Warping Vanilla Death Screen Glitch
Status:

At rare occasions, if someone were to continuously warping between islands either by launch pads or Fast Travel at a fast pace, there might a chance where the game will glitch and display a vanilla death screen. The reason for this is unknown. Clicking "Respawn" on the death screen will likely not wipe the inventory; however, the player's body will experience a death animation constantly glitching, similar to the Double Death glitch. Clicking the "Title Screen" or closing the player's game will be the safe options of avoiding it.

Dungeon Party Warping Inventory Wipe
Status:

If someone becomes a ghost in dungeons or dies at the end of a dungeon run and then get warped back into the same dungeon by their party leader after leaving, there is a chance the game bugs out and when the player types /lobby, all items in the player's inventory, including armor, are wiped. This has led to many players losing lots of valuable items.

Theoretically Infinite Ability to Auction Items on AH
Status: 

Players have the ability to put up a theoretically infinite amount of items on auction by using the quick auction feature where they click on an item in the initial menu they get when they click the auction.

From testing, players can go above 28 items and while they may not be displayed in the AH menu where they can collect the coins, they will still be shown on the AH.

Double Music (Minor)
Status:

In areas where music discs play as music, e.g. Dark Auction, the music disc will play multiple times out of sync.

Mining Fatigue
Status:

When the Dwarven Mines released, the Mining Fatigue status effect was added to all players to facilitate the new mining system. This rendered normally instantly breakable crops to take time to mine and also made some Fairy Souls unobtainable. This also made certain blocks unable to be insta-mined when they were able to before, like logs and gravel. The new mining system was disabled on private islands and Dungeons, but hasn't been fixed on any other island.

Update: Fairy Souls that had been unobtainable because of the new mining system have been made available by opening up blocks surrounding certain Fairy Souls. Mining fatigue has also been removed on the foraging islands.

Various Dungeon Boss Cheeses
Status:

"Cheese" is defined as making a boss stage much easier by using unintended mechanics.

Floor 7 - Necron: Various methods that bypassed the fight's restriction on movement abilities- like Bonzo's Staff,Leaping Sword, or Spirit Boots has been patched.

Floor 5 - Livid: The Eagle on the top of the room had a space behind it that allowed players to cheese the fight by shoving all Livids into a cramped space. there is now barrier blocks on the said spot.

Foraging Fortune Bug
Status:

As of the Dwarven Mines update, the double drop chance for Farming, Mining, and Foraging were changed to Fortune, which was the percentage chance of double drops, or triple drops when the fortune is over 100. However, players have tested this and found that, taking full advantage of the Treecapitator ability, they only got 35 logs from 35 blocks broken, regardless of Foraging skill or Monkey Pet.

Various Bugs with the Repelling Candle
Status:

When a Water Bucket is placed on a Repelling Candle, the torch in the candle with be washed away, leaving only the candle's base. This can be used to create many, many glitched items, including Mob Heads (And even dragon heads, which are only visible in 1.9+), placeable Command Blocks and Barriers and more.

/slimetest
Status:

For a brief while, the /slimetest command was accidentally made available to the public. This command allowed players to summon a Slime of varying sizes, meant to perform stress-tests on servers. This result in lobbies crashing, as huge slimes were summoned and caused chaos.

/killdante
Status:

Like the /slimetest command, this was also accidentally made available to the public. This command allowed players to immediately kill the Dante mayor in his Slime form and end the fight. Can be demonstrated in Technoblade's livestream or video.

Personal Deletor Bug
Status:

Hours after the Spider's Den revamp was released, there was an exploit involving the new accessory: Personal Deletors. If you put an Iron Sword in your Deletor, all swords that used the vanilla Iron Sword item would be deleted from your inventory. This included all expensive swords, such as the Giant's Sword and Hyperion. This bug caused players to lose hundreds of millions of coins.

Infinite Dungeon Potions
Status:

When you are drinking a dungeon potion, the effects will last forever instead of the set time for the potions.

Class level 0 visual glitch
Status:

In Dungeons, a bug makes the player look like an Archer 0 class. This could also happen on the Party Finder menu.

Ghost Weapons
Status:

At the moment, this glitch is unable to be exploited but that might change in the future. This happens when you open up the auction house menu then find a pricey item, like a hyperion, and click on it. Remember the name of the person who is auctioning it. Now head back to your private island. Do /ah player name. Find the item you clicked on earlier, click on it again, then hit the f key. If you are below version 1.16, this will not work. If it does work, then the item will appear in your offhand. If you try to move it to your inventory or go to a hub or use it's abilities, nothing will happen. So in that sense, it is a ghost item. Visible, but unable to be used or interacted with.

Update: Now if you try to move the ghost weapon from your offhand to your inventory or hotbar, it will usually disappear; but if you don't remove it from your offhand, the item will still keep on your offhand.

Mushroom armor's night vision
Status:

When you die wearing your mushroom armor, you don't have the permanent night vision after you respawn. Instead, you have to re-equip the armor again.

Dante Talisman still gets messages when being flung back
Status:

While you have a Dante Talisman, if you walk where the auction master is you get flung back back like always, but this time the goons still say you don't have a mask when you have a talisman. This glitch is likely due to being flung back triggers the Dante goons response.

Night saver bug
Status:

By placing a Repelling Candle, turning off your connection, and then breaking the candle and placing a Night Saver, you get a bugged coordinate. When turning back on your connection, if you don't crash and performed the glitch correctly, you will be left with a bugged coordinate that can manipulate Item Ids of that block, allowing you to get many previously unobtainable items.

This bug has been patched and no longer works.

It has returned in another form:

1. Place the Night Saver

2. Place the Launch Pad

3. Turn off the wifi

4. Break the Launch Pad

5. Place the Night saver

6. Turn on the connection

Spirit Pet Auto-Equips when leaving a Dungeon.
Status:

If you have a Spirit Pet of any rarity, when you leave a dungeon by warping out, the Spirit Pet will be auto-equipped, despite not being inside a dungeon. A workaround is to have an auto-pet rule set to auto-equip back to the preferred pet when entering the Dungeon Hub.

Decoy immune to Thorn's Spirit Mobs
Status:

Decoys cannot be killed by Spirit Bats and to a lesser extent, the Spirit Chicken. this is due to the mobs not having vanilla attacks.

Auto-Fails Experimental Table
Status:

As soon as you click on one of the panels for the main experiment, it will automatically fail the whole experiment.

Spider Boots in Dungeons
Status:

When wearing spider's boots in a dungeon, and then dying, one can no longer fly as a ghost. This can be avoided by switching to a different pair of boots before dying.

Swapping between Bonemerangs would deal heavily reduced damage
Status:

When you throw a Bonemerang and swap to another one or any weapon, the thrown bone would deal heavily reduced damage. The backward ability also wouldn't work.

This is the result of the new Anti Swordswap system, which also affect Bonemerangs. Confirmed by Minikloon that it's a bug.

Intimidation Accessores don't work with Magma Cube from Minions
Status:

Magma Cubes spawned by minions will attack players regardless of the player owning an intimidation accessory

Fire Aspect duration Stacking
Status:

The duration of the Fire Aspect enchantment can be stacked by striking the same enemy multiple times. Additionally, while Fire Aspect is ticking, holding a weapon with the Thunderlord Enchantment causes it to trigger every 3rd Fire Aspect tick.

F7 Flying Glitch
Status:

If you used either spiders boots, tarantula boots or spirit boots at the right time when entering F7 Boss fight, you would gain permanent creative mode flight that reset on death.

Zero Health Zombies
Status:



Glitched zombies have only been spotted on the server m823M, and they only spawns in the Graveyard. They have zero health and can't take any physical damage, thus you can't kill it. It has both regular Zombie and Zombie Villager variants. The zombies also don't have a moving animation.

Necromancy Mobs dealing knockback to mobs normally immune to knockback
Status:

Many bosses, such as the Endstone Protector, are immune to player knockback. However, Necromancy summoned mobs deal knockback to the boss.

Horse craft without collection (no quick-craft)

 * Status:

There is a glitch where you can craft the horse pet without having unlocked the recipe if you use a super enchanted egg. I did not use quick-craft for this and I crafted it when I was at around 28k leather collection. The glitch did not work with enchanted eggs. I am unaware of whether or not this glitch applies to any other pets.

status:not patched
to activate this glitch,you need a enchanting table and a weapon.to do this,you must open the enchanting table and put the weapon in the enchanting place and close it.as a result,the weapon will be invisable.if it has a ability, it will also activate it if you press the button that will activate.to fix this,open the enchanting table again,and close it
