Special Abilities

  • False Appearance: While the cobbleswarm remains motionless, it is indistinguishable from normal stones.
  • Shifting Floor: Whenever the cobbleswarm moves into a creature's space or starts its turn in another creature's space, the creature must succeed on a DC 13 Dexterity saving throw or fall prone. A prone creature must succeed on a DC 13 Dexterity (Acrobatics) check to stand up in a space occupied by the swarm.
  • Swarm: The cobbleswarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny stone. The swarm can't regain hp or gain temporary hp.

Actions

  • Stings: Melee Weapon Attack: +3 to hit, reach 0 ft., one target in the swarm's space. Hit: 15 (6d4) piercing damage, or 7 (3d4) piercing damage if the swarm has half its hp or fewer.

Bonus Actions

  • Shift and Tumble: The cobbleswarm pushes a prone creature in its space up to 5 feet away from it.
