Animagus

You can become an animal at will, similar to a druid's wildshape however, you must assume the same animal shape every time, decided upon at the beginning of the game, or upon receiving the feat. You can become an animagus, however it is very difficult and dangerous, fatal if done incorrectly, even slightly.  The creature must be of Medium size or smaller and must have a CR<2. The creature must also be a Beast. (You cannot become an Animagus if you are a druid.) Upon reaching level 8 you may cast cantrips. and use one handed melee weapons while in beast form. Upon reaching level 10 you can cast any non ritual spells up to 4th level. Upon reaching level 12 you can cast any non ritual spells. Upon Reaching level 20 you may cast any spells, including ritual spells and use any one handed melee weapons. (While spellcasting in beast form, you ignore any and all verbal components. Material components come from your player inventory.) While in beast form any armor you were wearing is negligible and your AC becomes 10 + your DEX modifier, your armour, as well as any equipped equipment will return to you upon resuming your humanoid form. While in beast form you gain the speak with animals spell and can cast it at will. Also while in beast form your stats become your player stats + the beasts stats modifier.
