can someone help me with a weapon mod?

[redboarder1]

I'm currently working on a weapon mod and I'd like to make the weapon cause a behemoth stagger like effect on a power attack. I'm not entirely sure how to do this. I'm able to get the effect to happen every time the weapon is swung, but I don't know how to make it happen only on a power attack. I'm beginning to think that it's only doable with a script, but I don't even know where to start with that. Anyone have any suggestions, or solutions? I'd really appreciate it.

Event OnHit(ObjectReference akTarget, ObjectReference akAggressor, Form akSource, Projectile akProjectile, bool abPowerAttack, \ bool abSneakAttack, bool abBashAttack, bool abHitBlocked, string apMaterial)
