UPDATE YOUR TOOLTIPS
So either the Deathfire tooltip needs to be updated or
Q needs to apply the keystone. His Q is a damaging ability even though it apply on hit effects. IT IS STILL AN ABILITY THAT I MUST PRESS TO USE IT!!!!!!!!!!!!!!!!! WTF!!!!!!!!!!!!!!!!! SO CLARIFY THE TOOLTIP OR SOMETHING AT LEAST BECAUSE BY ALL TOOLTIPS AND EXPLANATIONS IT SHOULD APPLY THE KEYSTONE WHEN IT DOES NOT!!!! and If you say its a basic attack well then it should apply
passive. So clarify something at least anything at all....... a simple excluding
Q in the tooltip or something
