Charge [Full][AoO: Yes]
Description: The combatant must move before attacking, not after. The combatant must move at least 10 feet and may move up to double base speed. All movement must be in a straight line, with no backing up allowed. The charge stops as soon as the combatant threatens the target. A combatant can't run past the target and attack from another direction.
After moving, the combatant may make a single melee attack or a bull rush. The combatant gets a +2 bonus on the attack roll. The combatant also suffers a -2 penalty to AC for 1 round.
Heh. I think I may have completely misunderstood what the original poster was asking. I thought Emirikol was asking whether you could cast a spell (say fireball), then do a charge attack.
Actually -- yes you CAN.
If you're hasted, pre-3.5, mind.
