Kayn q with conqueror

"Kayn dashes, then slashes. Both deal damage"

Kayn`s Q (Reaping slash) only gives 1 stack of conqueror. It deals damage twice and conqueror should proc on every attack or spell that deals damage. Whether you hit both of the attacks, only the first or the second gives only 1 stack of the conqueror rune. Feel like this should be fixed.

(Tested in Practice tool, both in form and out of form it gives 1 stack.)

Thank you!
