Actions

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit:2 (1d4 + 2) piercing damage plus 3 (1d6) force damage.

Reactions

Magic Allergy (1/Day). Immediately after a creature within 30 feet of the gremishka casts a spell, the gremishka can spontaneously react to the magic. Roll a d6 to determine the effect:

  • The gremishka emanates magical energy. Each creature within 30 feet of the gremishka must succeed on a DC 10 Constitution saving throw or take 3 (1d6) force damage.
  • The gremishka surges with magical energy and regains 3 (1d6) hit points.
  • The gremishka explodes and dies, and one swarm of gremishkas instantly appears in the space where this gremishka died. The swarm uses the gremishka's initiative.

Lore

Gremishkas are the vicious products of mistakes made by novice spellcasters seeking to create life. The results are cat-sized, magically unstable creatures with a taste for the trappings of magic—particularly spellbooks, spell components, familiars, and the like. Gremishkas delight in tormenting magic-users, holding vicious grudges against those who gave them life as they infest the walls of spellcasters' homes or the surrounding lands.
