Midigating Damage - Fighter encounter powers

[Abyssenia]

So i had a question about

Shield Riposte lvl1 encounter- so power is an Immediate Reaction. Trigger: Enemy Adjacent to you hits or misses you or an ally with a melee attack. on Hit 1d10 + Str damage and push target 1 square. You then shift 2 square to a square adjacent to the target.

the flavor text is "
Sweeping an attack aside, you strike with your shield while your foe is out of position."

Does this then stop the enemies attack and prevent the damage if you hit and push them out of range? pretty nice little power if thats the case

No. It's a Reaction, not an Interrupt, so the enemy gets their attack off before this move begins.

I do this routinely with my essentials knight using hammer hands stance, since opportunity actions/ attacks happen before the trigger.

But otherwise, yep what Pentius said.
