01Guide
Begin at Marrow Keep, then use each Beacon as a reset point for one nearby objective. Build around one Shell, one main weapon, a sidearm, and the Tarstones that support that plan; if an area keeps draining healing, open another route or change the loadout before forcing it. The goal is a repeatable plan, not a single lucky attempt with every resource spent. Keep the route small enough that you can return and adjust it safely. Test new equipment near a Beacon before carrying it into an unfamiliar boss arena.

02Walkthrough
Use the Fainweald route as a regional checklist: Prologue, Marrow Keep, Widow's Overlook, Mushroom Village, Sunken Village, Flooded Village, Blackridge Cliffs, Gloomshade Grove, Holding Cells, and Citadel of Penance. No complete late-game order is established here, so keep later regions flexible and use your active Beacon state to guide return trips. Finish a local objective, bank the route knowledge at a Beacon, and then take the next branch with a clear reason for entering it. This makes missed paths and optional bosses manageable instead of turning them into a restart. It also leaves time to return for nearby upgrades later. Recheck the nearest Beacon before committing to an unfamiliar dungeon or optional boss. Carry a familiar weapon until the return route and the nearest safe reset are clear.
