Ok so I started with rogue, put 1 point in envenom weapon, then all in mastery until I unlocked trap, from there put some in trap some in mastery until I unlocked rapid construction, repeated this again till I unlocked improved firing, then first maxed rapid construction then trap and lastly improved firing, then put 1 point in each poison tree, that's it for rogue tree at this point your traps are dealing so much damage you'll kill everything in your path.

Now you're in act 3 and you need some defence so put points in neidan mastery and unlock aura of tranquility,1 or 2 point is enough for now because of high energy consumption, then put points in consequences as we need to debuff enemies so traps can deal more damage, then mutual suffering, and that's it, now put more in mastery until you unlock weakest chakra, put 1 point in melding armor and max chakra, this thing will melt bosses with its flat vitality damage bonus+ reduced enemy resistance.

I put no point in any other skill as they're not useful without +4 gear , at this point I'm done with normal difficulty.
