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 to clear many stages and will already increase the power of your weapon tremendously.

Best Weapon Cores for the King’s Guard Lance:

Chill ATK (Free Augmentation)
Firearm ATK (Firepower Augmentation)
Chill ATK (Attribute Augmentation)
Fire Rate (Tactical Augmentation)
Bonus Firearm ATK vs Legion of Darkness (Special Augmentation)

King’s Guard Lance Lore Info

As Descendants began their work in earnest, humanity was able to expand their territory to beyond the land that had been taken from them. Within that land were the historical cities that once housed kingdoms. The “King’s Guard Lance” is a weapon that was created out of a relic discovered by an exploration party on a military reconnaissance mission.

The royal spear used in the creation of this weapon was discovered in the ruins of an ancient royal palace. When it was discovered that the red jewel inset in the spear could absorb an incredible amount of energy before emitting strong shockwaves into the air, it was developed into a weapon.

Upon analysis, this red jewel was found to be made up of components unavailable in Ingris. Its origins are still unknown.
