You use blood magic to twist the form of a creature into a monstrosity of unspeakable horror. An unwilling creature must make a Wisdom saving throw to avoid the effect. The spell has no effect on a shapechanger or a creature with 0 hit points.
The transformation lasts for the duration, or until the target drops to 0 hit points or dies. The new form can be any monstrosity whose challenge rating is equal to or less than the target's (or the target's level, if it doesn't have a challenge rating). The target's game statistics, including mental ability scores, are replaced by the statistics of the chosen beast. It retains its alignment and personality.
The target gains 50 temporary hit points. The target loses any temporary hit points remaining when it reverts 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.
The target's gear melds into the new form. The creature can't activate, use, wield, or otherwise benefit from any of its equipment.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the temporary hit points gained by the target increases by 25.
