This spell can be cast on any friendly unit of cavalry, a chariot, a ridden monster, a monster on its own, or a swarm. The target must be within 24" of the caster and must not be engaged in close combat.
If the spell is cast successfully, the unit moves 2D6" towards the nearest enemy that it can see. If no enemy are visible then it will not move. If in doubt as to which enemy unit is nearest, the caster may choose but must do so before rolling the distance. If the distance is sufficient to reach the enemy, the unit is deemed to have charged and all the normal charging rules apply, except that the enemy can only stand their ground - no other charge response is possible due to the speed of the spell.
