Shapechange - Minor

The character can take 1 minute to change into a form, from an ant to a bear. The character must know the form in order to take it. 

The character does not gain legendary actions or innate spells of the creature they change into, however they do gain any immunities, resistances, bonuses, or abilities (other then spells or spell like abilities)  but they also gain any vulnerabilities, weakness's, or negatives of the creature as well. They retain their HP in this form, but unless the form can talk they can't speak, and their AC becomes the AC of the creature.

The character must make a wisdom check ((DC 14)) or they remain stuck in that form for 1d12 days.

The character can only change into things up to 1/3rd their level in CR. The creature can be no smaller then an ant and no larger then a bear.

The character can't take any form that has a fly speed until level 10, unless their default race has a fly speed already.

The character can't take any form that has a swim speed until level 6, unless their default race has a swim speed already.

The character must do one of the following in order to learn new forms.

• Study the creature for 2-4 hours, learning its movement, habits, and behavior, the character must be able to be close enough to discern details.
• The character can spend an amount of time determined by the DM dissecting the creature, learning it inside and out.
• The character can devour the creature, letting their body learn the creature fully as it processes it's meal.
• The DM allows the character to know a creatures form for whatever reason the DM decides.

The character can choose to either have their equipment absorbed into them, or leave it behind in the change,  while equipment is a part of them, they gain no benefits from it.
