My fighter has 200 int points now. It can make me Hp wash five times per level,and Mp keep growing between 4 and 6. I mean that I finished five times hp wash (-20MP) when level up and there is still 4~6 mp remaining. In this case Could I remain the AP (not to do the Hp wash or add to the primary stats when level up) and keep leveling up? It means that I do not do the hp wash immediately when level up but I want to keep leveling up. Because My AP reset is not enough to Hp wash,I want to keep leveling up. I will do the Hp wash only if the AP reset is sufficient.
Warriors have a slightly higher HP gain range from reset AP than from level AP (50-55 HP compared to 50-54 HP). Yes, you can keep leveling on your fighter since there's no need to wash every level like a Night Lord.
So.... it means that I could retain my AP until I have the sufficient AP reset. and it doesn't affect even if my level up ?
Yes you do not have to use or spend your AP (Ability Points) right when you level. You can save them up until you have all the AP Resets required to wash.
