This build use Cinder Strike to trigger Explosive trap wich will trigger acid flask staking on burning shred and bruning effect !
For now its a leveling build but i didnt push far enough yet there is tons of question i had like:
-Is it better to stack on Atq speed or dmg ?
-In my node on acid flask i took dmg (fire bomb cocktail) but it may be better to take crit (Piercing debris) instead
-Wich skill is better ? Aerial assault or swift… i do prefer Aerial since i can reset it via other node and there is buff and great sustain with it but i wonder…
So anyway its a fun build for beginer to play just try to keep your Haste buff on and you are good !
It melt absolutly everything on leveling phase and its pretty tanky + it doesnt cost any mana !
Still to spend some mana put decoy and smoke bomb on your bar for boss or elite 
Im eager to ear what your through on this build so dont hesitate to tell me if there is thing you think i can improve !
