"HP Washing" With Full Resets?

1. It works

2. It can be done at 200. You can add points into MP while having a lot of int and you gain more MP/int that way. In fact, unless you're a mage, I'm pretty sure leveling up with extra int doesn't have an effect on MP anymore

3. repetition is limited by your funding in nx/the minimum MP formula. I'm absolutely terrible at explaining things so for the steps someone else will probably answer

4. 16 HP per point I think. Don't remember
