Sivir gains 50 movement speed for 2 seconds when she hits an enemy champion with her abilities or basic attacks.
Cost: 70 / 80 / 90 / 100 / 110 mana
Active: Sivir hurls her crossblade to a target location, which then returns to her. Enemies in its path take physical damage, with 10% reduced damage to each subsequent target, down to a minimum of 40%. Each enemy can be damaged only twice.
The damage reduction per enemy hit does not reset back to full damage upon changing direction.
Unlike other boomerang abilities, Boomerang Blade will still return to Sivir even if she dies before it changes direction.
Cooldown: 9 / 8 / 7 / 6 / 5
Cost: 40 mana
Active: Sivir's next 3 basic attacks bounce to nearby enemies, dealing a percentage of her attack damage to each additional enemy hit. There is no limit on how many enemies that can be hit, but each enemy unit can only be hit once per attack.
