your 1st question : Torso NAGA or REDEEMER. I suggest you to equip NAGA for much energy and phys ressistance. Because NAGA is NO 12 on the torso's tier list. and don't equip REDEEMER because it have less HP and res+energy.
your 2nd question : equip IRON BOOT OR POWER BOTTOMS.i suggest you to equip IRON BOOT.because it is the 4th no leg in the tier list. so good bye
