Behavior

It inherits the IM Spider's climbing, block-mining, melee, rally, support, and Nexus goals. It prioritizes players and allied defenders, then advances on the Nexus.

Drops

Base loot follows the vanilla Cave Spider table. Adult IM spiders also perform two independent 25% Small Remnants rolls through their shared IM drop logic.

Small Remnants • two 25% rolls

Vanilla replacement

An active Nexus converts vanilla Cave Spiders to this IM form at 30% of their former maximum health.
