Dive Impact damage is...

I think I got it (I hope), so that means ohs would have 50% reduced graze rate chance if the enemy is dazzled and critital rate has nothing to do with the graze calculation? Or did i misunderstood something?

 

It can only cancel graze rate upto 2x of the base correct hit but since critical rate can usually go more than that (upto 100%) it cant cancel the rest of the graze that occur due to miss being force hitted by crit. Weird exception here is barehanded, since it has 50% correct hit it would get 100% graze nulling making it 100% hit on dazzled enemy.
