Abilities

Resistance to Disintegrate

Disintegrate deals double damage, ignoring Hardness, rather than destroying the cluster heart outright

Crystal Surge

Trigger A non-elemental creature ends its turn adjacent to the cluster heart --- Effect The heart extends shards of crystal imbued with force, like a jabbing blade, and deals (3d10+20) force damage and (3d10+20) piercing damage to all creatures in a 20-foot radius (DC 40 reflex save). A creature who takes piercing damage from the surge is exposed to crystal corruption. On a critical failure, a creature also takes 2d6 persistent bleed damage.

Crystalline Corruption

Creatures afflicted by this curse slowly turn to solid crystal. This affliction's sickened, slowed, and paralyzed conditions can't be removed until the affliction itself is removed. Creatures with both the earth and elemental traits instead become carriers and suffer no ill effects aside from gaining the weakness to sonic. Saving Throw DC 40 fortitude Stage 1 sickened 1 (1 hour) Stage 2 weakness 5 to sonic and Sickened 1 (1 day) Stage 3 weakness 5 to sonic and Slowed 1 (1 day) Stage 4 weakness 10 to sonic and Paralyzed (1 day) Stage 5 weakness 10 to sonic, and the creature is permanently Petrified.

Description

A wave of magic passes through the area, causing crystal shards to grow and stab intruders.
