Yako Transformation

You make yourself--including your clothing, armor, weapons, and other belongings on your person--look different until the spell ends or until you use your action to dismiss it. You can change shape into an object of similar height and size. You can't shrink or grow into objects larger than yourself. Any objects you become maintain similar structural integrity although, performing this transformation to become an object, requires concentration. DC 12 saving throw if you are attacked to maintain form. For someone to discern you from an actual object, a creature can use its action to inspect your appearance and must succeed on an intelligence-Investigation skill check against your spell save DC. 

Using this spell to transform into an animal or person, said animal/humanoid being can be no more than half a foot taller or shorter than you. Your voice will not change along with your transformation but if you transform into someone who you know of, and intend to copy their voice, impersonating them. You must succeed in a DC 14 Charisma-Deception Skill check. On a fail, the creature being deceived will become possibly hostile. If you  succeed, said person is none the wiser. 

Kitsune are proficient in transforming into canine creatures of the same build, but cannot turn into creatures they have not seen face to face. While transforming, movement speed is 5ft per turn. The only action you can make while transforming during combat is dodge. 

I don't know how to make spells but this seems good but a little unfair idk. up to you
