Bucca

Flyby. The bucca doesn't provoke opportunity attacks when it flies out of an enemy's reach.

Sunlight Hypersensitivity. The bucca takes 1 radiant damage each minute it is exposed to sunlight. While in sunlight, it has disadvantage on attack rolls and ability checks.

Treasure Sense. The bucca can pinpoint, by scent, the location of precious metals and stones, such as coins and gems, within 60 feet of it.

Dagger. Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 5 (1d4 + 3) piercing damage, and the target must succeed on a DC 13 Constitution saving throw or become poisoned for 1 minute. The poisoned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Invisibility. The bucca magically turns invisible until it attacks, or until its concentration ends (as if concentrating on a spell). Any equipment the bucca wears or carries is invisible with it.
