Where To Find The Harbinger Of Hatred
To encounter the Harbinger of Hatred, you must first defeat Rahyeh, the final boss in The Black Sun timeline. It’s important to note that the Harbinger’s appearance is tied to thecorruption level of the timeline; higher corruption increases the likelihood of the Harbinger spawning. Specifically, the first Harbinger encounter becomesavailable at 100 corruption, with subsequent Harbingers appearing every 25 corruption levels thereafter, up to 300 corruption. Normal monoliths cap at 50 corruption, so you’re going to have to empower them. To unlock the empowered versions of all timelines, you’ll first need toclear the normal versionsof the timelines Spirits of Fire, The Last Ruin, and The Age of Winter.
After finishing those, head to the central island that connects the three timelines and interact with the chest there. Doing this will activate the empowered versions across the board, giving you access to tougher challenges and better rewards. Once empowered, run through the Black Sun timeline as usual, doing each Quest Echo (seen on the timeline’s stability bar) and maxing out its stability.

Corruption is a mechanic within theMonolith of Fatesystem that increases encounter difficulty and reward quality. As Corruption rises, enemies become tougher, but players benefit from higher item rarity, more experience, and increased chances for valuable Echo rewards.
