W: Ardent Blaze
You can W and E at the same time to cancel the W’s cast animation.
You generally want to use this when fighting, as the movespeed boost lets you chase and maneuver around skillshots.
Not too worth using to push, since it does very little damage and costs a lot of mana.
E: Relentless Pursuit
This spell is built for mobility and dodging.
You can interrupt your passive’s second attack’s animation with this spell.
So you would Q, auto, and as soon as you see the first shot go off, hit your E, and both shots will go off, but you’ll be able to get off your next auto attack faster.
In combination with your passive, its cooldown is very low, allowing you to use it multiple times to reposition and dodge spells in a teamfight.
When laning, you want to only use it if completely necessary, as it can eat up a lot of your mana you would want to spend on Q.
