Burning Aether for material Spoils
Spending Horde Aether on material Spoils converts a run into Obducite and gem fragments.
Aether Events during Infernal Horde waves, followed by the final Spoils chest.
Repeat with another Compass while material Spoils remain useful. Aether is collected and spent within each run; it does not carry over as a stockpile.
Stop when the material payout covers your next crafting goal or another Spoils option is more useful; use Nightmare Dungeons or Undercity Tributes for alternative Obducite runs.
