Aye-Aye

Sunlight Sensitivity. While in sunlight, the Aye-Aye has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

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

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

Dreadful Glare. The aye-aye targets one creature it can see within 60 feet of it. If the target can see the aye-aye, it must succeed on a DC 11 Wisdom saving throw against this magic or become frightened until the end of the aye-aye's next turn. If the target fails the saving throw by 5 or more, it is also paralyzed for the same duration. A target that succeeds on the saving throw is immune to the Dreadful Glare of all aye-ayes for the next 24 hours.

Finger of Death. The aye-aye points its skeletal finger at a target that has been paralyzed by its Dreadful Glare. It must succeed on a DC 12 Constitution saving throw or be cursed. The cursed target can't regain hit points, and its hit point maximum decreases by 10 (3d6) for every 24 hours that elapse. If the curse reduces the target's hit point maximum to 0, the target dies. The curse lasts until removed by the remove curse spell or other magic.
