Multiattack

The pustulent shambler makes three pseudopod attacks.

Pseudopod

Melee Weapon Attack: +9 to hit, reach 10 ft., one creature. Hit: 15 (2d10 + 4) bludgeoning damage plus 11 (2d10) acid damage, and the target must succeed on a DC 18 Constitution saving throw or contract the bonerot disease (see the Bonerot trait).

Absorb Flesh

The pustulent shambler feeds on a corpse within 5 feet of it. It regains 1d8 hp per size category of the creature it consumes. For example, the shambler regains 1d8 hp when consuming a Tiny creature's corpse or 4d8 hp when consuming a Large creature's corpse. The shambler can't use Absorb Flesh on a corpse if it or another pustulent shambler has already used Absorb Flesh on the corpse. If the corpse has intact bones, the shambler loses its Amorphous trait for 1 minute.
