Mind Stone Design
From my tries, I've been able to convert and transfer ~5 stacks of Armor Up to the opponent during a parry stun. Wouldn't it have been cool if you could transfer all the stacks at once with a heavy attack? I've had over 100 stacks after an SP3, but that only lasts 10 seconds. Nowhere near enough time to make use of them. Seems like the SP3 ability to double your converted Armor Ups is wasted. If I'm missing something let me know.
