Hi Henrique 
As far as I remember, you should be able to Restore it by Potion, Scroll or Spell. I wouldn't rely on Wiki too much in terms of Magic section, it is in a very early stage, not many spells listed there. We have definitely too few people to help:p
Are you sure you have not chosen the Warrior birthsign and Attacking Stance is not active? It gives -5 Endurance as well as -5 Heavy Armor.
Well... my birthsign is shown as a - in inventory. The game hasn't asked me to choose any birthsigns (like Oblivion asked me before we leave the sewers). When Nehrim will ask me this?
I do not know what is a stance, maybe I have none yet!
I am still in Gilliad vicinity, doing bounty quests at the local board. I've never been neither Stonefield nor Mage Sanctum.
I think this penalty was "acquired" after some combat in Crypt of Fetheran (sp?), a cave full of undead creatures (zombies, skeletons, acolyte skeletons and the like). Pretty nasty cave for my PC at 6th level, but I managed to defeat a creature like a ghost or a spectre in that cave (good loot from it, some pieces of armor set equipment).
Hope it helps you to help me!

Thanks!
Henrique
EDIT: I used a potion of Cure Disease and the penalty is gone! Problem resolved, thanks to all who helped me out!
