Equipment repair

Eligible equipment#

Weapons, armour and clothing must belong to the selected craft system’s repairable classes or its explicit special-item list. The item must be in your backpack or, under the current ML-enabled rules, equipped by you. An item at full durability cannot be repaired, and an item whose maximum durability is one or less is refused before another weakening attempt.

Using the current AOS-enabled rules, a weakening event removes one point from maximum durability and also reduces current durability by one, down to a minimum of zero. This roll happens before the repair success check, so a failed repair can still permanently weaken the item.

Weakening and success calculations#

Let C be current durability, M maximum durability and S the effective crafting skill or the skill stored in a repair deed. Weakening chance in percentage points is 40 + (M − C) − trunc(S / 10). The code compares that value with an integer roll from 0 to 99; values below zero never weaken and values above 99 always weaken.

After the weakening roll, repair difficulty is D = (trunc((M − C) × 1250 / max(M, 1)) − 250) × 0.1. An ordinary crafter performs the shard’s skill check over D − 25 to D + 25. A repair deed uses its stored skill directly: below D − 25 fails, at or above D + 25 succeeds, and between those points its chance is (S − (D − 25)) / 50.

A successful repair restores current durability to the remaining maximum. The repair code marks the deed for consumption after a valid attempted repair, including a failed attempt. These formulas describe the normal equipment branches; golem repair and special-item eligibility have separate checks.
