Gray Worm

The gray worm is a colossal burrowing horror that simply cannot be stopped — it shrugs off the conditions and spells that would halt anything else and grinds forward through earth and flesh alike.

• Negative healing.
• Inexorable The gray worm recovers from the paralyzed, slowed, and stunned conditions at the end of its turn. It's also immune to penalties to its Speeds and the immobilized condition, and it ignores difficult terrain and greater difficult terrain.
• Shake It Off [Reaction] Frequency once per day; Trigger The gray worm would be affected by a condition or adverse effect (such as baleful polymorph); Effect The gray worm negates the triggering condition or effect. Effects from artifacts, deities, or a similarly powerful source can't be avoided in this way.
