Gear Durability
Gear Durability, also known as just durability or Condition, is a mechanic where a gear piece will no longer increase a player's stats once the durability percentage reaches zero. When gear is broken (i.e. at 0% and no longer giving stats), the gear pips in the lower right will be red for that gear slot.
Durability is reduced by getting KO'd (2% durability), completing duties, completing FATEs, crafting, and gathering.
The Repair action
The general action 
Repair allows Disciples of the Hand to increase durability of gear up to 10 levels above them by 100%. This can increase durability above 100%, but gear can only be repaired when it is below 100%. This means the maximum possible durability is 199% (99% + 100%).
Repairs also require dark matter:
| Dark Matter | Max repairable gear level |  Gil price
|
|---|---|---|
 Grade 1 Dark Matter |
10 | 4
|
 Grade 2 Dark Matter |
20 | 12
|
 Grade 3 Dark Matter |
30 | 24
|
 Grade 4 Dark Matter |
40 | 48
|
 Grade 5 Dark Matter |
50 | 80
|
 Grade 6 Dark Matter |
60 | 120
|
 Grade 7 Dark Matter |
80 | 200
|
 Grade 8 Dark Matter |
100 | 280
|
Each DoH class (except 
Culinarian) can only repair some gear, depending on what material the gear is made from. The required class is noted in the gear's description.
- CUL cannot repair any gear, as there is no gear crafted by it.
- As of Patch 2.28, the player no longer needs to switch class to perform a repair.
Repairs can also be performed within instanced areas, and it is possible to request repairs from other players.
Mender NPCs
Mender NPCs can repair gear at the cost of gil, but only up to 100% durability - they cannot repair up to 199% like a player can. The cost scales depending on the amount of durability gained, and the equipment's level. The cost of a repair can be summarized with the following formula:
RepairCost = FullPrice * (1 - Condition)
- RepairCost = The final cost of the repair. This is rounded down to the nearest integer, but cannot end up less than 1 gil.
- FullPrice = How much the repair would cost if going from 0% to 100% durability. This depends on the gear's equipping level - see the table below.
- Condition = The current durability of the gear, in the form of a decimal from 0 to 1. For example: if the gear is currently at 65% durability, this would be 0.65.
- Note that the item description window rounds the durability down to the nearest integer. However, menders charge according to the "real" durability value that the player does not see. For example, a gear piece at 82.5% durability will display to the player as 82%, but the NPC will charge according to the true 82.5% value.
The value of FullPrice depends on the equipping level of the gear piece:
| Gear level range | FullPrice (0-100%) |
|---|---|
| 1 - 10 | 10
|
| 11 - 20 | 30
|
| 21 - 30 | 60
|
| 31 - 40 | 120
|
| 41 - 50 | 200
|
| 51 - 60 | 300
|
| 61 - 70 | 500
|
| 71 - 80 | 600
|
| 81 - 90 | 700
|
| 91 - 100 | 800

Cost comparison
Generally speaking, mender NPCs charge more gil-per-durability than the player would spend if they stocked up on Dark Matter and repaired their own gear. This can be observed by comparing the vendor prices of dark matter to the corresponding FullPrice value:
| Gear level range | Repair FullPrice (0-100%) | Equivalent Dark Matter cost | Dark matter savings |

| 1 - 10 | 10 |

Historical
During Legacy, durability caused the gear's stats to degrade gradually down to nothing at 0% durability. This is in opposition to how it currently works, where you have maximum stats all the way down to 1% and no stats at all at 0%.
