Check whether the artifact belongs to a different pool
The August demo update removes Watcher and Boombox from the demo and identifies them as Constellation-unique artifacts in the full game. That matters when searching for a named artifact: an item missing from the ordinary pool is not necessarily something more shop refreshes will solve. Check its Constellation association first. This dated note does not give the unlock steps, selection procedure or the full membership of each pool.
Keep the mode and progression scope separate
Playstack’s launch list includes more than 30 Constellations, six difficulties and a true ending, 13 Multiverse challenge modes, and Daily Challenges. Those labels describe different available content. They do not establish that a normal first victory completes the ending requirements, that every challenge has the same restrictions or that a mode unlocks at an assumed point.
