Arachne Fragments

Arachne Fragments are items similar to Summoning Eyes. In the updated Spider's Den (March 9th, 2021), there is a cave system similar to the Crypt in the Graveyard. You can get Arachne Fragments from killing Arachne. A way to get the first Arachne Fragment(s) is by doing a questline for the NPC named Shaggy. The boss that is spawned will have 20 Million Health. It is advised to have multiple people to fight it. The bosses summoned using Arachne Fragments will have less health.
