**R: Surge of power**
Active: Ryze unleashes a ball of pure magic at target location, dealing magic damage in an area and marking enemies with flux. For each enemy champion hit by Surge of power Ryze gains % magic penetration for 5 seconds.
Magic penetration: 4/6/8%
Balance accordingly. Would recommend lowering damage across the board, bounce damage and Q damage mainly. What this ult gives Ryze is reliable access to his AOE damage in team fights.
