Uagu:
I guess now is a good time to ask. How long does the mage armor spell last?
Mage Armor: Roll Forceful+Insightful. For every 4 you roll, an invisible shield will block the next 2 points worth of damage. This will also protect people immediately behind you. You cannot cast this on anyone but yourself, and
once you have a shield, you can't cast it again until it's used up. It only lasts about 5 minutes, even if it absorbs no damage.
So basically, until the end of whatever combat you're in, or about to get in.
