Monstrous transformation

Acts like a wild magic surge but for a creature transformation.

- once per round of combat when the player takes damage they must roll a d20 at advantage if a 1 is rolled they transform, if they succeed add 1 to the minimum roll for the next time they need to make the save, if they take psychic damage the advantage is negated and the limit of once per round of combat is ignored.

after the transformation the player must succeed on wisdom save DC equal to 20 minus their level or see all allies as hostile, the player must repeat this save each time they take damage the DC is however 15 minus their level. if they take damage as a result of an ally they will immediately fail the save. each turn after a failed save the player can choose to make a DC 30 - their level in order to return to a non-hostile state.
