01

Start with the retail list

Use the current retail achievement list as the source of truth. Beta achievements and preview lists belong in an archive note, not the completion checklist.

02

Mark missables before the first run

Say when to pause and check a side path, NPC, reward, or optional arena. If the retail missable state is unknown, label it instead of creating false urgency.

03

Keep a cleanup save

Before a major transition, keep a platform-supported backup where allowed. Never assume an optional encounter remains available after the next chapter.

04

Why this page refuses a fake trophy list

A completion guide is only useful when the achievement names and triggers match the retail platform. Beta lists, preview posts, and one forum screenshot are not enough to call a trophy missable.

Until the list is checked, use this page as a safe route: record optional Shells, dungeons, NPC hand-ins, sidearms, and bosses before major transitions; keep a supported backup; then do a cleanup sweep after the main path.
