A purple shield of energy engulfs the caster as he/she concentrates on returning the magical missile (fire ball, lightning bolt encluded). The caster must roll a successful wisdom(willpower), modified by the difference between the two casters lvls( -/+1 per 2 lvls different). If passed the missile can be directed back at the caster doing 3/4 of the damage rolled by the original caster, otherwise the missile if reflected in a random direction from the caster(**even at friends**).
