Treat each stone as its own objective
Voidstones are earned through specific endgame objectives. Use the endgame access planner to find the recorded entry requirements and keep your completion state separate for every stone. A boss name, invitation and entry item are related records, not interchangeable evidence.
Prepare the encounter you intend to run rather than buying inputs first and checking requirements later. Normal and Uber variants can share a destination while having different inputs and expectations.
Keep the Atlas plan honest
A Voidstone changes the Atlas context, but it does not replace map completion, defenses or a strategy for sustaining the maps you can run. After each objective, return to the map catalog and passive planner to choose the next attainable step.
This reference records access relationships and planning state. It does not estimate rewards, profit or encounter success.
