Does Staff of Provocation allow enemy attack himself?

Question

Suppose two players are fighting, and one of them has the Staff of Provocation (PHB2):

Power (Daily ✦Charm):Free Action.

Trigger: You hit an enemy with an attack power using this staff.

Effect: One creature of your choice makes a melee basic attack against that enemy as a free action. The attacking creature gains a bonus to the attack roll and the damage roll equal to your Intelligence modifier.

Can the player use this power on his opponent, and choose the opponent makes the attack against himself? Can he use this on his opponent, then choose himself to make the MBA against his opponent?

Answer 1

Can you make an enemy attack themselves?

Yes, you can. "One creature of your choice" means any creature, unless the power itself provides a limitation on that.

Some powers, such as the Sorcerer's Lightning Strike, have wording like this: "An enemy of your choice other than the target ..." - that limitation isn't made here, so the creature chosen can be the same creature you hit with the attack.

Can you target your enemy and choose yourself to make the attack?

Yes. There's no limitation preventing you from being the attacker.
