Arachne

Arachne is a spawned in the Spider's Den. She has two difficulties depending on her summoning method. Her weaker form has, but can spawn as a Runic variant on defeat of a stage. She 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. She can summon cobwebs and Arachne's broods, which have or. If Arachne is not defeated within 10 minutes of spawning, the message "Arachne is bored with your feeble attempt!" appears in the chat and she will then despawn.

Summoning
To summon the boss, one must place four Arachne's Keeper Fragments on the altar or one Arachne Crystal. 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, slowing down players that touch 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, she will summon 10 Arachne's Broods, which act similarly to Sven Pups, and spawn 20 more at another interval. These spiders are also immune to magic damage. After each interval, her runic state will be reset, meaning that a stronger version could start at, spawn 10 Arachne's Broods once lowered to , then reappear as a runic version with , spawn more broods once lowered to , and reappear as a normal version with.

If Arachne has not damaged a player within a certain duration (roughly ~6 seconds usually), she will use Venom Shot on whoever she is currently targetting. This debuff poisons you, lowering you to ~1% of your maximum health every few seconds. Note that 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), which is unfortunate but still occasionally happens. It should also be noted that the Vaccine Talisman does not protect the person inflicted with the venom shot debuff from getting poisoned. Another note is that 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.

 * You will be squashed like the WEAK BUG you are! (Upon dropping below 20% HP and all Arachne Broods are defeated)
 * You are lucky this time, you only called out a portion of my power, if you dared to face me at my peak, you would not survive! (Upon being defeated)

Greater Version (20,000,000 HP)

 * Hahahahaha, YOU MORTAL FOOL! You dare to summon me at my full strength to this plane, you are seeking death. With this power, I will not let a weakling survive here, this land will be a brilliant place to start a new invasion of my empire. Tremble beneath me if you wish to survive! (Upon spawning)

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 is an amazing choice for Arachne, because of its ability that allows you to latch on with the fishing rod and then left click to deal damage, as this works even if the boss runs away or there are cobwebs in the way, as long as you keep the rod 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, over Giant Killer.

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 might be related to Arachne, a mortal woman from the country of Lydia in Greek mythology, a great weaver who claimed to be better at weaving than Athena. She was eventually turned into a spider by Athena herself as punishment for her disrespect.
