"Increases master Yi's movement and attack speed and he becomes immune to all slowing effects temporarily. Additionally, killing a champion refreshes all of Master Yi's cooldowns."



I suggest changing it to something like this, just to clarify.

"Increases master Yi's movement and attack speed and he becomes immune to all slowing effects temporarily. Additionally, killing a champion while under this effect refreshes all of Master Yi's cooldowns."

It's clearly marked as an active skill without a passive component. That alone should clarify the conditions for the cooldown reset.
