Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d4 + 4) slashing damage plus 2 (1d4) acid damage.

Weakening Gaze. The babau targets one creature that it can see within 20 feet of it. The target must make a DC 13 Constitution saving throw. On a failed save, the target deals only half damage with weapon attacks that use Strength for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
