How this wiki marks its facts
Marks follow each fact: confirmed means official notes or the game itself shows it, reported means several players say so, and unverified means one source only. The full game launched on 9 November 2026, so most numbers come from Demo 7.0.1 and pages say when a value may have changed. How the wiki is made →
