Defeating Lesser and Greater Version of Arachne for the first time rewards.

Summoning
To summon the boss, one must place four Arachne's Callings (to spawn the Lvl 300 version) or one Arachne Crystal (to spawn the Lvl 500 version) on the altar made of endstone and sandstone located at. 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. It is recommended to use an Aspect of the End to escape upon noticing your hindered movement. You need to be at least level 15 to fight her.

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

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. A Cow Head can nullify the effect. This does not affect shields/absorption (i.e. a Necron's Blade Variant'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, Vaccine Ring and Vaccine Artifact do 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.

If Arachne is not defeated within 10 minutes of spawning, the message "" appears in the chat and she will then despawn.
