If you try to W -> Q -> AA in close range you might cancel your Empowered AutoAttack and not be able to use it at all afterwards.
1. Use W
2. Buffer Q right after pressing W
3. Press Attack on enemy
Because after W Pantheon immediately tries to autoattack the target and we cancel Empowered Autoattack animation with Q, Pantheon bugs out and refuses to use Empowered AA at all, even if you walk it out and try to attack again.
