In Horizon Zero Dawn, modifications—referred to as Coils for weapons and Weaves for outfits—play a crucial role in customizing Aloy’s combat effectiveness and survivability. They serve to enhance both offensive and defensive capabilities, allowing players to tailor their loadouts based on personal preferences and the demands of various encounters.

Coils: Enhancements for Weapons
Coils are specialized upgrades that can be applied to ranged weapons, targeting key weapon stats. Each coil typically offers a primary effect, such as increased damage or improved handling, alongside potential secondary or tertiary effects. Notably, these enhancements are governed by the weapon’s inherent capabilities—meaning a coil cannot bestow capabilities such as frost or shock damage to a weapon that is incompatible with these elements. Any unused effects are essentially wasted if they don’t align with the weapon’s base characteristics.

Types of Coils:
1. Damage Coils: These coils focus on enhancing the physical damage output of compatible ranged weapons. The degree of enhancement is contingent on the coil’s rarity, with rarer coils providing more substantial boosts.
2. Corruption Coils: These specific coils enhance corruption damage, making enemies more susceptible to negative effects, while also hindering their ability to resist such damage.

Weaves: Enhancements for Outfits
Weaves serve a complementary role by augmenting the defensive capabilities of Aloy’s outfits. They can bolster resistances against various elemental damages—like fire, shock, and cold—alongside enhancing certain offensive capabilities, such as protecting against ranged or melee attacks.

Weave Benefits:
– Elemental Resistances: Players can equip weaves that target specific elemental threats they anticipate facing, improving their survivability during combat.
– Offensive Bonuses: Some weaves also provide enhancements related to attack resilience, ensuring that Aloy can endure encounters with more formidable foes.

Rarity System
Both coils and weaves are classified by rarity: Common, Rare, and Very Rare. The rarity of the modification significantly affects the extent of the stat boosts provided. Higher-rarity enhancements often offer superior boosts or simultaneously enhance multiple stats, allowing for more effective customization.

Versatility in Combat
A standout feature of modifications is their malleability—players have the ability to switch out coils and weaves even during combat. This dynamic allows players utilizing skills like Tinkerer to swiftly adapt their strategies, equipping different modifications as the battle landscape changes.

The Frozen Wilds DLC
The Frozen Wilds expansion introduced unique coils and weaves that are tied to specific locations. These modifications yield powerful bonuses but come with the caveat of being untradeable and indestructible, emphasizing their special role in gameplay without the risk of dismantling.

Conclusion
In summary, modifications in Horizon Zero Dawn serve as a pivotal mechanism for enhancing both weapons and outfits, providing players the opportunity to customize their combat style and adapt to challenges effectively. By focusing on offensive stats with coils and defensive capabilities with weaves, players can create a tailored approach to meet the varying strategies required to overcome the game’s formidable adversaries.
