Lux Ability (LoL): Prismatic Barrier

Lux throws her wand to a target location, bending the light around herself and any friendly champion it touches by granting a 45 / 65 / 85 / 105 / 125 (+35% of ability power) damage shield for 2.5 seconds. After reaching maximum range, the wand returns to Lux, shielding herself and any friendly champion it touches for the same amount again. The second shield stacks with the first shield while also refreshing the shield duration.
