Grave Worm

The Grave Worm is a ranged undead enemy found in The Boneyard. With 10 HP (20 in champion form), a range-5 ranged attack, and movement 4, it is a mobile long-range harasser that keeps distance while dealing consistent damage. It leaves no corpse on death, making it unusable for necromantic or corpse-interaction abilities.

The Grave Worm's defining survival mechanic is burrowing: when hit, it immediately digs underground to evade follow-up attacks. While burrowed, it is not subject to most tile-based hazards such as bear traps, allowing it to reposition freely across dangerous terrain. It will surface on a later turn and continue attacking, making it a recurring nuisance unless eliminated quickly.

Area-of-effect attacks that hit the tile it burrows into, or abilities that trigger damage on movement, can damage the Grave Worm even while underground. High-damage single-hit abilities that can one-shot it prevent it from burrowing at all. In The Boneyard it often appears alongside melee undead such as Shamblers, so prioritize the Grave Worm's ranged pressure while keeping defenses up against the closer threats.
