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 Wizard or an enemy unit that it can see. If no enemy are visible then it will not move. 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.
