Irelia Ability (LoL): Flawless Duet

Irelia sends a blade to the target location for 3.5 seconds. Flawless Duet can be recast after 0.15 seconds while the blade is active, and does so automatically at the end of its duration, though not if she is channeling Teleport.

RECAST: Irelia sends a second blade to the target location, or to her current position if Flawless Duet was recast automatically.

Once both blades have been placed, they fly toward each other regardless of distance and converge over 0.25 seconds, afterwards dealing 80 / 125 / 170 / 215 / 260 (+80% of ability power) magic damage to all enemies within a line between them and stunning them for 0.75 seconds, during which they are revealed.

Flawless Duet's recast can be used during Bladesurge and the cast time of Vanguard's Edge. Each of the blade's travel times are 0.264 seconds.
