Arachne

Arachne is a spider boss summoned in Arachne's Sanctuary in the Spider's Den.¹

Summoning. Place items on the end stone and sandstone altar in the sanctuary:¹

• four Arachne's Callings summon the weaker, level 300 version, much like placing eyes for a dragon;
• one Arachne Crystal summons the stronger, level 500 version, which needs Combat level 15 to fight.

The first kill of each version gives SkyBlock XP.¹

How the fight works:¹

• Every hit on her does at most 1,000 damage, and she and her brood are immune to magic and arrows.
• At 50% and 20% health she splits into 10 and then 20 Arachne's Broods; she comes back once the whole brood is dead.
• If she hasn't hurt anyone for about 6 seconds, she fires Venom Shot at her target, a poison that drags you down to about 1% of your health. A Cow Hat cancels it, and absorption shields still work through it.
• If she isn't dead within 10 minutes, she gets bored and despawns.

Loot tip: if she dies next to a wall, part of the loot can land on the floor above.¹
