Riven's abilities charge her blade for 5 seconds, causing her to do 20 / 25 / 30 / 35 / 40 / 45 / 50 % of her attack damage as bonus physical damage on her next basic attack. Riven can store up to 3 charges, and can only expend one at a time.
Runic Blade's empowerment will not be consumed if the attack misses.
The buff timer for Runic Blade refreshes whenever Riven gains or consumes a stack.
Active:Riven steps forward and lashes out in a series of powerful slashes, dealing physical damage to all enemies within 112.5-range. Broken Wings can be cast two additional times within 4 seconds, with the timer resetting after each.
All three strikes deal the same damage, with the third damaging enemies within 150-range and knocking them up. Riven will target the unit under your cursor; if no targets are present, Riven will simply strike the direction she is currently facing.
