As two actions, you fuse the flesh of a creature that you can touch or see within 10 meters. The creature must make a Fortitude saving throw. If the creature is not composed of flesh, the spell has no effect on it.
On a failure, its flesh ripples, grows together, and fuses into a nearly seamless whole until the end of its next turn as it is paralyzed and is forced into a fetal position (if humanoid), with only the vaguest outline of its folded arms and legs visible below the all-encompassing wave of flesh. The target retains the ability to breathe, eat, and excrete.
A shapechanger can revert to its normal form on its turn.
You can target one additional creature for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
You can expend 2 additional mana so the duration changes to 1 minute/mana, concentration and the creature’s flesh is warped for the duration. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
