Ezreals Q cant Crit

...yes

It applys on hit effects, but the bonus damage of the Q won't crit.

It's intended to prevent abuse. It'd be like a Yas who doesn't have to dash closer to crit your face.

Yes. Not every ability that applies on-hit effects is meant to crit, and vice versa.

Looking at you, Pantheon.

If it crit, the ability would deal:

70/110/150/190/230 + 220% Total AD + 80% AP without Infinity Edge

87.5/137.5/187.5/237.5/287.5 + 275% Total AD + 100% AP with Infinity Edge

AYY LMAO
