Don't buy separate pieces everywhere, come buy FULL SET with all the right rolls.
As the title stated, you're buying helm, 2 shoulders, chest, 2 gloves, pants, boots

Material Damage set I have several upgradable pieces for higher price.
They all have the right rolls, such as + all res, transfer time reduction, rage/willpower cost reduction, either %dmg or %material dmg on every slot.
