Traits

Fanatic Advantage. Once per turn, if the dragonfang makes a weapon attack with advantage on the attack roll and hits, the target takes an extra 10 (3d6) damage.

Limited Flight. The dragonfang can use a bonus action to gain a flying speed of 30 feet until the end of its turn.

Pack Tactics. The dragonfang has advantage on an attack roll against a creature if at least one of the dragonfang's allies is within 5 feet of the creature and the ally isn't incapacitated.
