De-Fusion

Choose one "Fusion" creature or object that you can see within 120 ft. of you. The creature/object is split back into the creatures/objects used to create it (the object must be neither worn nor carried).  Any damage the original fused creature/object had sustained is carried over and split evenly between the components, but conditions (including Attunement) previously effecting the fused creature/object are ended.  Split creatures must wait until initiative turn 20 before re-rolling for initiative and are unable to perform any other action until then apart from rolling saving throws.

An unwilling fused creature can make a Wisdom saving throw, and if it succeeds, it isn’t affected by this spell.
