Use available Expedition fragment stages to make gradual progress toward an eligible Valkyrie rank-up.
Dorm > Expedition; choose an available stage that explicitly lists the desired Valkyrie fragments.
Expeditions can provide a steady, low-attention way to collect fragments for a Valkyrie when a matching fragment stage is available. The roster of stages is not universal: availability determines which character fragments you can target, so verify the exact stage before committing stamina. This guide is for fragment collection through the Expedition interface; it does not promise that a particular Valkyrie will always appear. Pick a character you already intend to develop, start its available stage, and return to claim the result. Add collected fragments to that Valkyrie’s rank-up progress, then decide whether to continue or redirect stamina to another need. Treat this as incremental collection rather than a fast one-time unlock. If the target’s fragment stage is absent, wait for availability or pursue a different current objective instead of spending on an unrelated stage.
Repeat while the desired fragment stage is offered and stamina is available. Stage availability is conditional; this is not a guaranteed permanent route for every Valkyrie.
Stop when the target rank-up is funded, the stage disappears, or another current progression need is more valuable.
