Haven’t written a Shadowrun Quality in a while, how about this one?
Price of Power
Cost: 5 Karma
Magic has a price, and you’re willing to pay it. When you make a check as part of a spell, you may choose to take stun or physical damage up to half your magic attribute (round up). For each point of stun you take, you add one die to your check. For each point of physical you take, you add two dice to your check. These may not be healed via magical means, but can be healed through treatment or normal healing.
