Fafnir

Fafnir is an Enhancement in Darksiders III. When equipped, it grants the following effects:

• Active Effect: Boosts physical/arcane damage for the slotted weapon based on held soul count.
• Passive Effect: Reflects a portion of damage received back on the attacker.

Location

The Fafnir Enhancement may be obtained by speaking to Usiel after defeating Lust, regardless of whether Usiel is incapacitated during the fight.

Usiel is located near the Festering Pool Serpent Hole in the Bonelands. Travel away from the stairs and around the shipping containers till you reach the outside, where angels are fighting some undead. Continue straight past them towards the small water pit and use the Mansk to climb up. Then turn left immediately towards the second water pit and use the Mansk to climb up. Usiel will be found inside the angel's outpost to the left.

Upgrades

To fully upgrade an enhancement (By speaking to Ulthane), a total of 12 Angelic Artifacts, 12 Demonic Artifacts and 1 Essence of a Chosen are required. The materials and fully upgraded stats remain the same regardless of whether choosing the Angelic or Demonic path. Each enhancement comes with a flavor quote that changes depending on upgrade path and hints at the origin of the enhancement's power.
