Effect
This spell transforms a willing creature that you touch into a horrific monstrosity. 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 an aberration with a Challenge Rating of 4 or lower.
The target’s game statistics, including mental ability scores, are replaced by the statistics of the chosen aberration. It retains its alignment and personality.
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. As long as the excess damage doesn’t reduce the creature’s normal form to 0 hit points, it isn’t knocked unconscious. 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.
In addition to a delerium fragment worth 100gp, you must provide either the heart or brain (or equivalent organ in the case of aberrations with a truly alien physiology) taken from a creature of the same type: the organ must either be recently harvested or magically preserved via gentle repose or similar magic. As part of casting the spell, you drive the delerium fragment into the organ, and both are consumed by the spell.
The Game Master determines if an aberration’s physiology makes its organs suitable for use with this spell.
