Cherub

Radiant Burst. The cherub bursts into radiant energy when it drops to 0 hit points, releasing bright light in a 10-foot-radius sphere centered on itself. Creatures in that area must succeed on a DC 12 Constitution saving throw or be blinded for 1 minute. A blinded creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Multiattack. The cherub makes two short sword attacks.

Short Sword. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 1d6 +2 slashing damage. 

Radiant Eye. Radiant light emanates from the eyes of the cherub as the cherub targets one creature it can see within 60 feet of itself. The target must make a DC 12 Wisdom saving throw, taking 6 1d12 radiant damage on a failed save, or half as much damage on a successful one.

Float. The cherub moves up to 20 feet vertically in one direction without provoking opportunity attacks. If it ends this movement suspended in the air, it hovers in place. It can’t be knocked prone while airborne.
