"Double" and "Triple" HP Washing?

Level up
5 AP into MP with over 300(?) INT (from gear/base INT)
Reset 5 into HP out of MP
Reset 5 into HP out of MP
Reset 5 into Str/Dex/Luk out of MP


So in theory, if you had enough MP you could Wash 4, 5, 6 times? Not that anything past 2 would be at all practical.

Fixed for triple. You do not need to take off your INT gear (I forget the total INT needed though, and I am too lazy to calculate it right now), just fyi. But yes, you could wash 4+ times assuming you have the MP leftover still.
