if i upgrade magefists and the battle gauntlent is anything less than 71 defense is there no way it can possibly hit 98 defense when i up to crusader? like only go for the double upp if you hit 71 on the nose right?

I think it doesnt matter Im not 100% sure, the final step Will be 59-68 def from white crusaders gauntlets x 30% Ed

Só i think it doesnt matter cause it Will multiply in final form.

Doesn't matter. Defense will be re-rolled.
