Benefit

As a swift action, you can spend an arcane spell slot to force nearby enemies to move away from you. Each opponent within 30 feet of you must begin its next turn by moving at least 5 feet (1 square) away from you. The direction of movement doesn't matter, as long as it takes the foe farther from you than the square in which it started. Unless the enemy designates the movement as a 5-foot step, this movement provokes attacks of opportunity as normal. A successful Will save (DC 10 + the spell slot's level + your Cha modifier) negates this effect. This is a mind-affecting enchantment (compulsion) effect.
