i have a Dark knight. can i put a lot of points in the HP and then wash them (put from the MP to STR ) or i need to do it once at a time. ( put 1 AP to HP then AP rest from MP to STR) is there any difference ?
Both works, it doesn't matter. What matters is how big of an MP pool you have. The bigger the MP pool, the more washes you can get from it. http://royals.ms/forum/threads/fully-revised-hp-washing-guide.8286/ is a very good guide on HP washing and it's not too hard to understand either.
