Not at all. Only really the paladin. Given you only heal with exura or exura gran.
Since Exura (gran) san or exura (gran) ico is biased on level and skills per distance and weapon. I believe it is at least.
from ML 0 on a knight you'd get to magic level 12 no more than 70% left to 13. Since 12 is 17kk and 13 is like 635kk.
And for a paladin from ML 0 to 30-32 spending 50-100kk
where spending 118kk on a mage you'd get ml 100 from ml 0.
All were just normal mana potions.
EDIT: adding details.
