Keen Hearing. The Zubat has advantage on Wisdom (Perception) checks that rely on hearing.

Sunlight Sensitivity. While in sunlight, the Zubat has disadvantage on attack rolls.

Leech Life. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 2) piercing damage, and the Zubat regains half as many hit points.

Supersonic (Recharge 5-6). The Zubat emits a disorienting screech that targets a creature within 60 feet of itself. If the creature can hear, it must succeed on a DC 10 Constitution saving throw or be subjected to the effect of the spell Confusion. At the end of its turns, an affected creature can repeat the saving throw. If it succeeds, the effect ends for that creature.
