Arachne

Arachne is a spawned in the Spider's Den. She has two difficulties depending on her summoning method. Her weaker form has, and can be summoned with 4 Arachne's Keeper Fragments, similar to dragon fights. She also can be summoned with one Arachne Crystal, spawning a stronger version with. This can be done at the altar made of endstone and sandstone located at. Arachne can spawn as a Runic variant on defeat of a stage. Arachne can summon cobwebs and Arachne's Broods, which have or. If Arachne is not defeated within 10 minutes of spawning, the message "" appears in the chat and she will then despawn.

Summoning
To summon the boss, one must place four Arachne's Keeper Fragments or one Arachne Crystal on the altar. After placing the four fragments, the spider will spawn after a short delay, and displaying a line of dialogue explaining how much of a mistake the players have made.

Behavior
After it spawns, Arachne will run around, damaging players around it. Wherever it walks, it leaves a large wall of cobwebs behind it. It is recommended to use an Aspect of the End to escape upon noticing your hindered movement.

Upon dropping below 50% and 20% hp arachne splits into a number of Arachne's Broods (10 for 50% and 20 for 20%) These spiders, like Arachne, are immune to magic damage. Once all of the brood are killed Arachne will respawn. Arachne has a chance to respawn as runic.

If Arachne has not damaged a player within roughly 6 seconds, she will use Venom Shot on whoever she is currently targeting. This debuff poisons players, lowering them to ~1% of their maximum health every few seconds. This does not affect shields/absorption (i.e. a Valkyrie's Wither Impact/Wither Shield). To counter this, using Wither Impact/Wither Shield about 1 second after taking a Venom Shot will allow you to regenerate health (i.e. with Life Steal) while your shield is active. If you do not have access to a variant of the Necron's Blade, it is recommended to disable Dodge/Agility potions to allow Arachne to damage you, which means she won't use Venom Shot. Sometimes Arachne will 'refuse' to hurt you (likely a bug). It should also be noted that the Vaccine Talisman does not protect the person inflicted with the venom shot debuff from getting poisoned. Additionally, the venom effect does not expire on death, meaning on your way back to the boss room you are still at risk of dying to spiders along the way.

Strategies
Arachne is immune to all forms of magic and ranged damage, meaning the only way to damage her is through melee attacks. The Phantom Rod works well against Arachne, as once you hook her with the fishing rod you can use the left click ability to damage her, as long as the rod stays attached. Ferocity/Attack Speed builds are optimal, and the Tiger Pet is the recommended pet for this boss.

Allowing Arachne to melee attack you will delay her from using Venom Shot. In the event that you receive the venom effect, having an option like a Necron's Blade with Wither Shield or Wither Impact means you can activate the shield and rush when a wave of Arachne's Broods spawn, allowing you to use to restore your health quickly (before your shield expires). Without a Necron's Blade this is still possible, but the timing needs to be much more precise. Due to this boss having 900 defense, Titan Killer is more effective than Giant Killer.

It is worth noting that by equipping the Cow Head, the player can ignore the venom effect as it grants immunity to de-buffs.

Lesser Version
This version is meant for early game players due to her weaker attacks and lower HP. However, this does not mean you do not need proper gear, as she still packs quite a punch. To survive, the recommended are the following.


 * Ender Armor is viable if you can afford it. It is not recommended to fight Arachne before this.
 * If you have enough money, any form of Dragon Armor is enough to fend off her attacks.
 * Recluse Fang is a good early game weapon if one cannot afford the stronger swords.
 * Aspect of the Dragons is a great all around weapon that's affordable for even mid-game players.
 * Any damage boosting pet, such as Tiger Pet or Enderman Pet, are great choices for additional DPS.

Greater Version
This version is meant for late and endgame players due to incredibly high HP, stronger Venom Shot debuff that can instantly bring one down to incredibly low health, and higher damage reduction. The recommended are the following:


 * Shadow Assassin Armor, Elegant Tuxedo, Necron's Armor, and a Scorpion Foil are not recommended for the lesser version due to its heavier damage cap.
 * The most optimal build (especially while solo-killing Arachne), is to have a Necron's Blade variant (preferably Valkyrie) and full Werewolf Armor. This is due to the damage cap.
 * Using a Cow Head makes you immune to her Venom Shot attack, making it incredibly useful.
 * Phantom Rod is a very good weapon to deal damage to Arachne as it bypasses the need of going through webs to attack her, making it incredibly useful
 * While the Golem Pet's Toss doesn't deal damage on Arachne, it does still toss her up, acting as a large nuisance to anyone trying to hit her. The 20% chance to reflect attacks also translate to 20% damage reduction, and a reflected attack negates the Venom Shot's initial hit, but not the venom/poison effect itself.

Bugs

 * If Arachne is defeated next to a wall, only some of the loot will appear on the ground. The rest will spawn on the next "floor" up. In order to get the rest of the loot, you will have to travel directly upwards. It is most commonly located above ground.
 * Loot from this boss can spawn one or two blocks above the void as well.

Trivia

 * Arachne is a reference to the mythological character Arachne, a mortal woman from the country of Lydia in Greek mythology. She a great weaver who claimed to be better at weaving than Athena, and was turned into the first spider by Athena as punishment for her disrespect.
