I do not quite understand how the double wash. It would be like that? I wash 2 per level. > Add 2 points DIRECT IN MP. > Retreat 2 points MP and lay in HP with AP RESET. > Retiro 2 more points MP and put the desired attribute with AP RESET. That right?
Assuming you already put the prerequisite 1 AP to HP, that's how it works. You'll need base Int on order to benefit from Double/MP washing.
