Gumienniki

Shapechanger. As a bonus action, the gumienniki can change its form into a Tiny housecat, or back into its true form. Its statistics, other than its size, are the same in each form except it loses its flaming hand scythe attack when in cat form.

Flaming Hand Scythe. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) slashing damage and 7 (2d6) fire damage.

Fiendish Blink (1/Day). The gumienniki flashes its glowing eyes, illuminating a 15-foot cone. Each creature in that area that can see the gumienniki must succeed on a DC 12 Constitution saving throw or be blinded for 1 minute.

Taunting Cackle. When the gumienniki is missed by an attack, it can taunt the attacker. The attacking creature must succeed on a DC 12 Wisdom saving throw or have disadvantage on its next attack roll or saving throw.
