Always be aware of how little health you have.
While remembering how hard you can hit (you will learn this soon enough).
All offensive skills (Q,W&R) + your exhaust spell (F) can be combined for the ultimate weapon.
I usually start by unlocking Alpha Strike (Q) first (hide in bushes and use with exhaust for first blood) as it can secure some easy kills early on.
Wuju Style (E) has reasonably low mana usage which is good and this means you can use it often.
Wuju Style passively increases your attack damage but if you active it (active by pressing E) its effects will double for a short time, however after using this your attack damage will drop until the passive effects of wuju style kick back in and return your attack damage to its original level.
So don't use it at the start of a massive team fight because you will be hitting hard and then you will be hitting twice as hard for a bit and owning then your attack will drop lower than it started out for a few seconds and this can cost you your life.
Highlander (R) is an attack/movement speed boost good to use combined with Wuju Style (E) to rip down turrets in a hurry! and Great used in conjunction with wuju style (E) & Alpha Strike (Q), all three of those dropped on an enemy will leave a really big dint especially if you have your blood thirster.
