Mana bug
 

Is there any way i can edit my max mana ?
Im using a mod for instant mana regen and so far i noticed i got +50 or 60 mana from it. At lvl 15 my max mana is 148 but with all my items and talents it should be @ 90. im guessing most of the extra mana is "illegally" gained from this exploit.

Use shift ~
then type mana 1
then type mana value your wish to have.

Ty for your answer. Also , this wont affect my game/game play in any way, right ?

You cannot calculate what your max mana is at your level - there are shrines which give you +5 mana all over the game - dont just calculate your talents and items.

I know that but i noticed i got 30 mana from nothing while checking old save games.
All i did was win a fight then enter a cave. Next save i had +30 mana so id like to remove that at least.
