The catalogue combines in-game descriptions, original practical summaries and attributed community references for acquisition and buyers. Each source keeps its applicable version. A listed item is not proof that it can be obtained in every Demo build.
The default or base price is fixed game content. The actual sale price can change through in-game mechanics and random events.
A displayed item description is a game text reference. Gameplay effects remain pending unless a separate guide records a verification.
