Prophecies - The Hermit - Death of Boss

I dont quite understand how to “fullfill” the Prophecies in the game… I have a Prophecie, The Hermit - Death of Boss - Monolith, I have gone througt several Monolith with bosses and killed them but nothing happens…

Can someone explain what I have to do?

You may have to kill a specific number of Bosses, or complete it at a minimum Corruption level to fulfil the requirements.

strange in monolith

Found out, I thought it was bosses but no… Killed an Exiled Mage and boom, prophecy fulfilled :blush:. Thanks :blush:
