GRAIN ROT Weapons, Durability & Repairs Guide
How tool durability works, when to carry a backup, how stronger weapons unlock and what is known about repairs.
Direct answer
The starter mallet is a demolition tool with limited durability, so bring a reasonable backup instead of depending on one tool for a whole run. Stronger combat options unlock through Outpost inventory progression and Murch's stock. The full release includes an Enchantment & Repair Machine, but costs and exact repair steps can change, so use the prompts shown by your current build.

How durability works
Tools do not last forever. Current beginner coverage specifically calls out the mallet's durability and the risk of breaking the last one halfway through a profitable route. Watch the live durability indicator rather than relying on a fixed swing count: target type, balance patches and the item itself can change how long it lasts.
The mallet is a demolition tool, not your best weapon
Biggy's tutorial identifies the starter mallet as a tool for breaking weaker constructs into scrap. It can help in an emergency, but community walkthroughs warn that Corrupted are often too dangerous to treat the mallet as a general combat answer. Preserve it for the objects that fund the run and use cover, traps or escape routes when a fight has no clear payoff.
Bring a backup without wasting inventory
A current extraction guide demonstrates placing a small number of spare tools on the elevator floor before departure. That gives the crew replacements without filling every carried slot. Do not stack excessive duplicates: the same guide reports that older items can disappear when the limit is exceeded. Bring enough to recover from one break, not a pile you cannot account for.
How stronger weapons unlock
Upgrade the Outpost room tied to inventory and Murch's merchandise. A community max-room demonstration from the demo shows Compass access at the first inventory tier, a gun at the second, and a sword plus hammer at the third. Treat that order as version-sensitive: confirm Murch's current stock after each room level instead of assuming an old screenshot is permanent.
How to repair equipment
Launch materials confirm that version 1.0 adds an Enchantment & Repair Machine. If the machine is not yet usable in your save, continue the Outpost quest flow and room progression until its feature is introduced. Once available, follow the machine's current item, currency and confirmation prompts. This guide does not publish a fixed recipe because reliable official costs were not available and balance updates can change them.
Common durability mistakes
Do not use the last healthy mallet on low-value clutter when the crew still needs scrap-producing targets. Do not carry an expensive weapon into a run you are already planning to abandon late. Do not assume a gun makes an aggressive route safe: noise, stamina and positioning still matter. Most importantly, extract a valuable tool instead of gambling it on one more room when the vessel is already damaged.
