Disembody Self

You separate your flesh, body, and skin into their constituent parts. You transform into a fleshmire, a skeleton, and a skinmeld, each appearing in an unoccupied space within 5 feet of you. If there is no available space, those undead creatures are squeezed into your current space instead.

Your statistics are replaced by the statistics of the undead, except you retain your mental ability scores, alignment, and personality. As such, you can’t cast spells or speak. You assume the hit points of the undead, and any active effects affecting you continue to affect all of your new forms. All of your gear melds into the new forms, except for any nonmagical weapons you designate that are available in the undead’s statistics.

All three undead share your initiative when you first cast this spell, but otherwise roll for their own initiative in future combats. If a single source of damage affects more than one undead, you only make one saving throw to maintain concentration on this spell.

The transformation lasts for the duration, or until all undead drop to 0 hit points or die. When the spell ends, you revert to your normal form in the space of one undead of your choice (if more than one undead remains), or the space where the final undead died. When you revert, you return to the number of hit points you had before the transformation. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form.
