Force shapechange

Force shapechange was a common spell used by shugenja in Kara-Tur. The spell was very rare outside Kara-Tur.

Effects
When cast, this spell forced a shapechanger to reveal their true form. During casting, the shugenja pointed at the creature they suspected of being a shapechanger. Transferring into their true form took several minutes and was extremely painful for the shapechanger.

Components
In addition to verbal and somatic components, the spell required a material component, a live butterfly. It was released while the shugenja uttered the verbal components.
