You gesture at a creature you can see within range, magically molding them into a new form. The spell has no effect on a creature with 0 hit points. An unwilling creature can make a Charisma saving throw to resist the effect. If they fail, they can repeat the save at the end of each of their turns, ending the spell on a success. The transformation lasts for the duration, or until the target drops to 0 hit points. The new form can be any beast whose challenge rating is 4 or lower, and equal to or less than the target's CR or character level. The target's game statistics are replaced by the statistics of the chosen beast. It retains its alignment, personality, allegiances, and broad plan of action. The target assumes the hit points of its new form. When it reverts to its normal form, the creature returns to the number of hit points it had before it transformed. If it reverts as a result of dropping to 0 hit points, any excess damage carries over to its normal form. The creature is limited in the actions it can perform by the nature of its new form, and it can't speak, cast spells, or take any other action that requires hands or speech. Its items meld into the new form, and the creature can't activate, use, wield, or otherwise benefit from any of it.
