Available to MU 3+. Sacrifice a Risk Die by rolling it. If you succeed, add 50% to the damage the spell inflicts — calculate dice totals first, then add 50% of that amount. Intensifying a spell is dangerous: if your Risk Die comes up '1', you suffer 2d8 arcane backlash as your attempt fails. Successfully intensifying a spell of at least 3rd level results in a gain of one percentile point to your Intelligence, Wisdom, or Charisma — your choice.
