Mastery or Haste?
Weapon ilvl is a huge part of your damage, and is what you should prioritize your rolls for. Good news is that the three bosses in the first three wings that drop weapons are tier bosses, so if you don't have the tier set, then your coins will be used for tier and weapon. And Thok, who drops bis weapon and tier head, also drops bis trinket. Your other bis trinket comes off Galakras.
