Beast Morph

The caster can mutate one body part of their body into a small dragon-like creature head, capable functioning as normal but must stay attached to the caster. The beast can do multiple things, including: 

-Using a sense of smell and giving the caster a chance to roll two dice instead of one for investigation and perception checks.

-They can bite, giving the caster an extra damage roll for unarmed strikes using the body part replaced by the beast. (But no extra roll for ac roll)
