Cackler

When the cackler dies, it releases a dying laugh that scars the minds of other nearby creatures. Each creature within 10 feet of the cackler must succeed on a DC 11 Wisdom saving throw or take 2 (1d4) psychic damage.

The cackler can mimic any sounds it has heard, including voices. A creature that hears the sounds can tell they are imitations with a successful DC 11 Wisdom (Insight) check.

The cackler's innate spellcasting ability is Charisma (spell save DC 11, +3 to hit with spell attacks). The cackler can innately cast the following spells, requiring no material components:

At will: fire bolt

1/day: Tasha's hideous laughter

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage.

Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 6 (1d6 + 3) slashing damage.
