For batteling you will wear a light armor or even robes (Dim Mak) and a small/medium shield + Morning Star as weapon. As any tank try to cover your resists and imms as best as you can + mord and breach imm for starters. When you can or found something with it, add stun, daze and confusion immunity in your gearsetup. Main exotic you need to cover for hells is magic, but have something with pos (stygia, cania) and divine (mainly bosses) at hand to switch to.
For doing the rogue duties you can just switch the gear around as you need to max out your skills. Lvl 50 Rogue armor + Song + Maze Rouge Amulet + thids rogue gloves should put all you need to the maximum (search, disable trap, disable lock).
