Assassin/Ninja heavy hybrid inferno (ish)

I think this is good spin and single hit damage for heavy hybrid (idk tho LOL this might be like bad bad). need help to increase the mana tho I dont think its enough to sustain, probably sparkweaver? but that will hurt the damage. also if someone can make a crafted ring to replace yang for the mana steal + damage please do it LOL im suck with crafted, thanks !

(also if you can comment smth about this build, like if its bad or if theres smth I can improve, please do. shit on it if you must LOL but I really wanna get into class building so any advice will help a lot)

 

When I used heavy hybrid Inferno I used Sparkweaver both for mana and to patch elemental defences.
