GRAIN ROT: How to Repair Weapons
Use this grain rot how to repair weapons guide for a direct answer, practical steps and current troubleshooting.
Repair checklist
The machine shows whether an item is eligible and displays the cost before payment.
| Step | Action | Status |
|---|---|---|
| 1 | Progress until the second Outpost floor is available | Required |
| 2 | Bring the damaged item to the repair device | Required |
| 3 | Interact and read the displayed price before paying | Required |
| 4 | Budget 100 gold for a full repair | Cost may change |
| 5 | Check durability before leaving the device | Complete |
Where to repair equipment
The repair system does not appear as an early construct in the build menu. Its device is on the second Outpost floor, so a missing repair option usually means the required progression is not complete.
If the device is not present, finish the active Outpost objectives, return to each quest giver and make sure the save belongs to the full release before troubleshooting the item itself.
The safest repair sequence
Bring the damaged item to the second-floor device, make sure the machine accepts it and read the displayed cost before committing. Budget 100 gold for a full repair, but follow the amount shown on screen if it differs.
Do not promise that every consumable, tool or special item can be repaired. Eligibility can differ from ordinary weapon durability, and some devices may reroll or modify an effect instead of restoring ammunition in the way a player expects. Read the prompt attached to the actual item.
Repair, ammo and rerolls are different questions
Staple-gun ammunition and hammer durability are separate systems. The repair machine restores eligible equipment durability; it does not automatically refill ammunition or replace every special effect.
If an item has a special effect the player wants to preserve, verify the device description before use. There is not enough official documentation to promise that every effect remains unchanged.
Rule out a client display bug
Patch 1.08 fixed a bug where clients could see the wrong durability values on items. In a multiplayer session, an incorrect display can make a valid repair look unsuccessful or make a nearly broken item look safe. Compare the host and client state after updating to the current patch.
Restarting into the same outdated build will not resolve a fixed replication issue. Confirm the patch number and allow Steam to finish the update before retesting. If the problem remains, the official Discord FAQ directs technical issues to the support-ticket route.
Why an old save can change the diagnosis
The official launch FAQ recommends a new save because quests, balance and progression changed from the demo and playtest. An old save that loads does not guarantee that every Outpost trigger migrated correctly. Test the same progression on a fresh save before calling the second-floor device absent for everyone.
Keep a backup before experimenting with local save files. Patch 1.08 improved behavior around renamed and copied save slots, but that does not turn every manual edit into a supported workflow. The guide does not recommend downloading replacement saves.
Repair limits
The machine decides whether an item can be repaired and shows the current price before payment. Special effects, ammunition and durability are separate values, so read the complete result before committing.
Major updates can add rooms, devices or new item classes.

Keep reading
Complete the opening Outpost tasks, Quill’s story work and the rescue/key objectives in the quest log. Return to the giver after each step; the second-floor door opens through the completed quest chain. Once inside, Tink, room upgrades and the repair/enchantment machine become available.
Best WeaponsThere is no single best weapon for every run. Use a sword for controlled melee, a hammer for combat plus demolition, a mallet for early furniture breaking, and a firearm when a dangerous target must be stopped at range. Solo players should keep a ranged emergency option whenever ammunition allows.
Latest UpdatePatch 1.09, released August 28, 2026, is the latest available build. It improves Grinder navigation, fixes the Vibe Modulator, changes resting recovery to percentage-based values and resolves several clipping and saved-item issues.
Quests & ProgressionFollow the quest log through Biggie’s maintenance tasks, Spark inspection, the first Deep Layers extraction, Quill’s Ancient Facility records, the rescue and second-floor key arc, Tink’s room tasks and the Corrupted Elite objective.
