Possible mana bug...

Was trying out the mana system and noticed something odd. For that character at least, the higher my wisdom score got the more mana it took to cast all spells. Also the amount of mana needed to cast even lv 1 spells seems to be quite high though I don't know whether that is intended or not?

Are you low vitality?

How high is your wisdom?

Tested with 17 cleric lvs, max wis was 20, full vitality

Hmm, interesting...

If you can give full details, that would hep see where the problem is. Here's the stuff that matters:
Class levels / character level
Spell name, metamagic if used, spell cost
Intelligence and mana pool size
Wisdom and soul vitality
Charisma and regeneration rate.

With those things, I can see if everything is working right or wrong.
