Target one unengaged enemy unit within 24". A subtle whisper in their minds suddenly persuades many warriors to change their allegiance and attack their comrades. All the models in the unit immediately make one attack against the unit itself. Roll to hit, to wound and take saves as normal (counted as an ongoing combat, so no charging bonuses, weapon rules only applicable in the first round of combat, etc). Characters who have joined the unit are not affected or attacked because of their strong will. All mounts are unaffected. After this moment of folly, the troopers revert to normal and the spell has no further effects, but if the unit suffers enough casualties, it must take a Panic test. Units Immune to Psychology or fleeing are not affected by this spell.
