Modifications are items in Horizon Zero Dawn that can be added to Aloy's equipment to increase stats and perks. Coils are modifications applied to weapons and weaves are applied to outfits. They can be obtained from Treasure Boxes and looting machines.
Modifications come in three types; Common, Rare and Very Rare with the amount of increase in the given stat depending on the rarity. Some modifications can provide a boost to more than one stat at a time.
Coils are modifications that can be added to weapons to increase damage dealt or handling stats.
- Damage Coil
- Fire Coil
- Freeze Coil
- Handling Coil
- Shock Coil
- Tear Coil
- Spear Damage CoilFW
In the base game, the minimum modification value for all weapons coils is 6% and the maximum is 50%. For coils with more than one effect, the maximum secondary value is 20% and the maximum tertiary value is 12%. The only exception is the Spear Damage Coil, which provides a single effect with a maximum value of 30%.
Weapon coils can only be used to augment a weapon's existing abilities and not add new ones. For example, Fire Coils cannot be added to the Sharpshot Bow because it cannot deal any Fire damage. If a coil provides more than one benefit, the primary effect will determine what weapons it can be applied to. This means that coils with multiple effects can sometimes be added to weapons that will not benefit from the secondary and/or tertiary benefits.
|Hunter Bow||Damage, Tear, Fire, Handling|
|Sharpshot Bow||Damage, Tear, Handling|
|War Bow||Freeze, Shock, Corruption, Handling|
|Tripcaster||Damage, Fire, Shock, Handling|
|Sling||Fire, Freeze, Shock, Handling|
|Blast Sling||Damage, Handling|
|Rattler||Damage, Tear, Freeze, Shock, Handling|
Weaves are modifications that can be added to outfits to increase resistance to different types of damage or increase stealth stats.
- Resist Corruption Weave
- Resist Fire Damage Weave
- Resist Freeze Damage Weave
- Resist Shock Damage Weave
- Resist Melee Damage Weave
- Resist Ranged Damage Weave
- Stealth Weave
In the base game, the minimum modification value for all outfit weaves is 6% and the maximum value varies depending on the weave's effect. Elemental resistance weaves have a maximum value of 33%, the stealth weave has a maximum value of 25%, and range/melee resistance weaves have a 20% maximum. For weaves with more than one effect, the maximum value of secondary and/or tertiary benefits is 12%.
Unlike weapons coils, outfit weaves can add new abilities to outfits and are not bound by the defense already provided. For example, although the Nora Protector outfit does not provide Fire resistance, a Resist Fire Damage weave can be applied to add that ability.
The Frozen Wilds DLC adds eleven unique modifications to the game which are found in fixed locations. Once obtained, they can be dropped, but cannot be dismantled or sold.
Each one counts for 8⁄11% (≈0.73%) Frozen Wilds game completion.
