Full SDG (really no point for STG) if you have bless you will be beast. Weapon - spear and shield. Learn zap for melee (speed gun destroys) and you can whirl/vf as well. Subclasses should be self explanatory lol.. Chi - It depends, what is your BP and normal BP of your server? If you have lower BP go HP, Immunity, Break, and PATK in all gates including jiang hu. Same thing with higher BP, except you would switch out break for pstrike ( wars have insane defense and with the amount of HP you can get now a days it is easy to pot breakthroughs. But you will never pot a higher BP's pstrike if they have decent-great attack)
Block for shield, maybe headgear if you can survive. If not go with the HP one. P6 souls on everything except for the boots. Get P3 ones for those (they add 10pct break)
