Kalista Auto Attack through Elise Cocoon [GAMEPLAY]
Kalista is cocooned by Elise mid Auto Attack and continues to Auto Attack through the stun only placing rend stacks when someone is close enough to be hit with a Runanns bolt. This only places the rend stack on the Runanns proc and only does the damage from the Runanns proc NOT the auto attack.
Not sure how easy this will be to reproduce or is common. Recorded a video to make it easier to see.
