Maintenance
Maintenance supports repairs with repair kits and at a grindstone; higher skill eases grindstone use, extends kit life, and allows repairs to more damaged items.
How it works
The original-game perks page says Maintenance allows repair of items with repair kits and weapons at a grindstone. At higher skill, the grindstone is easier to use, repair kits last longer, and more badly damaged items can be repaired. The skills page also describes repairs with kits and at a grindstone. Exact repair costs and damage thresholds are not supplied.
Read the supporting references
A source-bounded reference to original-game skills affecting combat, equipment upkeep, alchemy, horse handling, gathering, thievery, reading, and stealth. It describes supported effects and progression facts, not a complete skill catalog, optimal builds, or comparative performance. Guidance explains the referenced mechanics; it is not a tested damage ranking. Check the stated edition and source version before applying a patch-specific detail.
