Wereowl

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

Keen Hearing and Sight. The wereowl has advantage on Wisdom (Perception) checks that rely on hearing or sight.

Shapechanger. The wereowl can use its action to polymorph into an owl-humanoid hybrid or into a giant owl, or back into its true form, which is humanoid.
