Pyro

Pyro

Class	Weapon Mod

Pyro is a weapon mod for Power weapons that turns part of each shot into fire. A share of the weapon's damage becomes Thermal damage. Each hit also has a chance to set the target on fire with Burn. It suits a Power weapon build that wants extra damage over time without changing guns. Pyro is available from the early game, since weapon vendors can stock its lower tiers.

Effect

Pyro has two parts. The first part converts some of the weapon's damage into Thermal damage. The share is 15% at Tier 1 and 50% at Tier 5. The total damage stays the same, but part of it now counts as fire.

The second part is a chance to apply Burn on hit. Burn is a status effect that deals fire damage over time. The chance is 3% at Tier 1 and 15% at Tier 5. Fast firing weapons roll that chance more often, so Burn shows up more with assault rifles and submachine guns.

Pyro is worth the slot on a Power weapon with a high rate of fire, where many small hits give many chances to Burn.

How to Get Pyro Guide

Check weapon vendors, which sometimes stock Tiers 1 to 3.
Skip time by a day and check again if it is not on sale.
Combine a matching pair at the crafting menu to raise its tier.

Upgrades

Pyro comes in Tiers 1 to 5. Each tier converts more damage to Thermal and raises the Burn chance. A matching pair of the same mod and tier can be combined at the crafting menu into one copy a tier higher. A mod can only go on a weapon of the same tier or higher. Once installed in a weapon, the mod stays in that weapon.

Character Builds

Pyro suits any build that shoots Power weapons. In the Reflexes tree, Ready, Rested, Reloaded lowers the Stamina cost of shooting assault rifles and submachine guns. Mind Over Matter lowers recoil while aiming. Spray And Pray lowers the Stamina cost of hip fire. In the Body tree, Dread lowers enemy Armor when V uses ranged attacks.
