Weapon Readjustment
You can use the Weapon Readjustment at the Weapon Workbench in Albion. Here are the best Weapon Readjustments for the Sigvore’s Proof:
- Explosive ATK
- Fire Damage
- Firearm Critical Hit Damage
- Firearm Critical Hit Rate
Try to upgrade the Weapon Readjustments to at least purple quality.
Weapon Cores
Weapon Cores juice up your damage quite tremendously. However, especially the later-level Weapon Cores are difficult to get. So start with whatever weapon cores you have available. Weapon Cores drop in the Void Erosion Purge endgame activity.
Higher level Weapon Cores drop in the higher level Void Erosion Purge levels in The First Descendant. However, you can gradually work towards the highest level. I recommend trying to get to level six as soon as possible, since it won’t require clearing many stages and will already increase the power of your weapon tremendously.
Best Weapon Cores for the Sigvore’s Proof:
Firearm Critical Hit Damage (Free Augmentation)
Firearm Critical Hit Damage (Free Augmentation)
Explosive ATK (Firearm Augmentation)
Fire ATK (Attribute Augmentation)
Grappling Hook Recharge (Precision Augmentation)
Fire Rate weapon cores are important on the Restored Relic launcher. Additionally, you can swap out Chill ATK for any other attribute depending on enemy weaknesses!
Sigvore’s Proof Launcher Lore
![]()
This firearm is the result of the sustained efforts of one Descendant who was obsessed with explosions. This Descendant was inspired when he witnessed a Vulgus named Sigvore of the Legion of Darkness easily controlling an explosive weapon.
Although he was the enemy, the Descendant could not help but marvel at the power of bombs. The Descendant proceeded to follow Sigvore and record everything he learned about his weapon. Later, he seized the weapon for himself and submitted it to Albion to use for development purposes.
The Weapon Development Department, impressed by the Descendant’s passion, reverse engineered and duplicated the weapon according to his wishes and developed a brand new launcher. They added an extra Sticky Bomb inside the launcher for additional firepower.
This weapon was originally set to be named “Esiemo’s Proof” after the Descendant who had made its creation possible, but Esiemo adamantly opposed this name, so it was changed to “Sigvore’s Proof.”
