The Forgotten Knights are one of the most important endgame factions in Last Epoch, presiding over the Harbinger system. Harbingers are powerful bosses that appear within the Monolith of Fate, serving as some of the toughest challenges the game has to offer. With enough Last Epoch gold to protect you, the task will no longer be difficult. Defeating them rewards players with Last Epoch gold rare loot, exclusive crafting materials, and Unique items tied specifically to this system.
If you plan to take on Aberroth, the ultimate boss of Last Epoch, you'll first need to align yourself with the Forgotten Knights. This faction not only represents a major step in your endgame progression but also grants powerful rewards as your reputation increases.
Unlocking the Forgotten Knights
You first encounter the Forgotten Knights after battling your initial Harbinger. To trigger this event, you must complete the level 90 Monoliths-Spirits of Fire, The Last Ruin, and The Age of Winter. Once you've cleared two of them, the third will be altered: its third Quest Echo boss is replaced by a Harbinger.
Defeat this Harbinger and, upon leaving the Echo, you'll be transported to the Shattered Road, the stronghold of the Forgotten Knights. Here, a Forgotten Knight NPC will invite you to formally join their faction.
Unlike item-based factions that limit you to a single choice, Last Epoch allows you to join all endgame factions simultaneously, so there's no downside to aligning yourself with the Forgotten Knights as soon as they become available.
Building Reputation with the Forgotten Knights
Reputation with this faction doesn't work like it does with standard item factions. Instead of completing faction quests or grinding favor, your rank increases each time you kill a new Harbinger at the end of a Monolith Timeline.
This design ensures that as you progress toward facing Aberroth, you're simultaneously advancing with the Forgotten Knights. Each Harbinger you defeat contributes to your rank and unlocks increasingly powerful benefits.
However, accessing new Harbingers isn't as straightforward as replaying quest nodes. To encounter additional Harbingers, you'll need to build up Corruption in Empowered Monoliths.
Corruption begins at 100 and increases as you complete Echoes.
Higher Corruption boosts enemy health and damage, but also improves rewards such as item rarity, crafting materials, and experience.
The higher your Corruption climbs, the tougher each Harbinger encounter becomes-ensuring that each step toward Aberroth is more challenging than the last.
Once every Harbinger has been defeated, you can face Aberroth himself. This ultimate boss is accessible through the Shattered Road, requiring you to spend a Harbinger Eye to buy Last Epoch gold initiate the fight.
