How do MP\HP work???

i mean wel ...
how do i know what i need?
like if my hp is 2500 do i go to medium or small or large? ofc not xl
same for mp if mine is 7600
cuz im wasting all i got on pots ...

Pots heal much more than it says. This is becouse it depend on sou'r str and int distribution...more str you have, more HP will heal you (HP potion), same story for MP (int).

I suggest you to use lower pots and when you'll get --Cannot use skill due infucient MP--or lot of deaths-- switch to higher grade potion.

I hope I helped you

im lvl 34 xbow/cleric atm and I use only medium pots,MP pots say that they heal 340MP,but they heal full MP for me,with Hp is almost same.. :)
