Hp Washing without leveling?

I just tried this on my hero and gained only 20 hp per ap(did three). Does improving max hp not factor into this? I would assume I should be gaining 50 hp per ap... help

Unfortunately, as said just above me, it is not recommended for either warriors or Bucs. Those classes must actually level and place points into HP to receive the maximum gains; however, the method is perfectly fine for all other classes (except possibly mages, but they usually don't HP wash).

It is worth noting too that placing from MP>HP will always give you the minimum gain whereas placing directly into HP from a level up will give you a range (so you could gain 0-~5 more HP per point). I had washed around 25 points or so after I hit 200 so I can promise that it works (and it is the cheapest method for HP washing without leveling, to answer the OP).
