Description
You experiment with raw, primordial magic, which is as unpredictable as it is powerful. You may choose to cast any spell you have not learned, but if you do, make an Arcana success check: if you do not roll exactly clean success (11 or 12), a chaos surge occurs and affects the encounter, as determined by the GM. Roll a d6: on a 1, there is collateral damage; on a 2, your spell has unintended targets; on a 3, something is gained and something is lost; on a 4, there is a transformation or reversal; on a 5, the spell is out of control; on a 6, the spell costs twice as much to cast. Probability spell checks explode on a 5 or a 6.
