Tempering and mission materials
Loot Netherscape and Crucible equipment
Underworld exploration and floor clears provide repeated chances to collect equipment while progressing through endgame floors.
Throughout an Underworld floor: first the Netherscape, then the Crucible after using an opened portal.
Repeat across available floors and runs for equipment attempts. Specific items, Graces, and effects are not guaranteed.
Stop when the next boss is too risky or you have collected enough useful gear for the current build goal. Resume after preparing or when another floor better matches your target.
