Once you enter the endgame phase in Last Epoch, not only will the game mechanics become more complex and difficult, you will also encounter more dangerous bosses. Sometimes these bosses are even closely related to each other - you must defeat one to find the next higher-level boss.
Take Harbinger Of Hatred as an example. Only by defeating him can you move on to challenge the pinnacle boss Aberroth, but to unlock the encounter with Harbinger Of Hatred, you need to kill the final boss Rahyeh in The Black Sun timeline. Based on this, we will give you a priority to introduce you to how to defeat this “intermediary” boss.

How To Unlock The Fight?
Of course, as we have already mentioned, you must defeat Rahyeh first, and then the probability of Harbinger Of Hatred appearing is related to your Corruption level. Corruption is a special mechanic in Monolith of Fate system. The more Corruption you have, the more dangerous the enemies you encounter will be, but they will also provide more rewards.
Harbinger of Hatred begins appearing when you have 100 corruptions, and a new difficulty level unlocks for every 25 corruptions (up to a cap of 300 corruptions). To get as much Last Epoch Gold as possible from Harbinger of Hatred, as well as other rewards, you’ll need to clear the normal versions of the timelines Spirits of Fire, The Last Ruin, and The Age of Winter.
How To Deal With The Fight?
Before you start fighting Harbinger of Hatred, you must defeat Rahyeh, The Black Sun in the same fight, as it can be tricky to deal with both bosses at once. Harbinger of Hatred is a tanky boss that defends itself by absorbing damage and negating your AOE attacks, so you’ll need to be on the move and fully aware of its attack patterns to defeat it.
The boss’s weakness is that there’s a vulnerable gap between two powerful attacks, which is when you can deal with damage. Here are all of its attacks and how to deal with them.
1. Tank Slam
The boss will use this skill to form a cone-shaped ground slam that will cause physical damage to you. When this skill is activated, the boss will raise the hammer, which can be used as a sign to sidestep to avoid the attack.
2. Massive Tank Slam
This skill has a larger range of slams and will be accompanied by a red warning, which will cause severe physical damage to you. The way to deal with it is to quickly move out of the red warning area to avoid the attack.
3. Tank Echo Slam
Harbinger Of Hatred and its echoes use this skill to launch a series of slams at you, sending out physical and void damage lines. You need to place yourself between the echo lines as much as possible to avoid the related damage.
4. Tank Void Combo
The boss will launch three consecutive weapon swings, which will bring powerful ground slams. To avoid this attack, you must stay away from the boss during the combo and re-engage after the last slam.
5. Tank Void Orbs
This skill allows the boss to summon lingering orbs that deal void damage when they come into contact with you. To avoid them, you must keep moving and avoid hitting these orbs.
6. Tank Void Portal Blast
When this skill is activated, the boss will open a portal and smash it through with his hammer, dealing physical and void damage to you. Therefore, when the portal appears, you must immediately move away from the portal to avoid the attack.
7. Tank Void Rush
Harbinger Of Hatred will rush forward with this skill and deal physical and void damage to you. The damage caused by this boss skill can be dodged laterally.
8. Tank Void Turrets
The boss will use this skill to deploy orbs that will shoot void projectiles at you in a straight line. To avoid this attack, you need to stay as far away from the line of fire of the turrets deployed by the boss as possible.
Best Gear And Modifiers
After understanding Harbinger Of Hatred’s combat skills, you also need to equip reliable gear and modifiers to make your Last Epoch character more powerful in order to easily deal with this boss. I believe you have already discovered that this boss mainly causes physical and void damage, so the following types of gear and modifiers will be more targeted:
Gear:
- Void Resistance
- Movement Speed and Mobility Skills
- Health and Armor
Echo Modifiers:
What Rewards Can You Get After Completing The Fight?
After defeating Harbinger Of Hatred, in addition to basic gold or XP, you will also get some unique items, and rewards related to Forgotten Knight Faction, including:
- World Splitter: A powerful two-handed axe favored by Void Knight.
- Harbinger’s Needle: A consumable idol that can be equipped and used to defeat empowered timeline bosses to gain an additional Gaze of Orobyss - allowing you to gain more Corruption when defeating Shade of Orobyss.
