This spell can be cast on any enemy unit of cavalry, a chariot, a ridden monster, a lone monster such as a Great Eagle, or a swarm. The target of the spell must be on the tabletop and must be engaged in close combat.

If successfully cast, any creatures in the unit (but not their riders), will cower and therefore require 6s to hit in that turn's Close Combat phase. If 6s are required anyway, the creatures may not attack.
