I use stealth kills on overlords all the time. You just run to the wall in the chamber and make sure the over lord followed close enough and stay crouched up there and you can stealth dive his ass lol,(reply>), @Joe Bloniarz also did u know there's a way to replace the 2nd epic trait, the one that the game says you can't Replace? Yea there's a way now,(reply>), @Joe Bloniarz I'm tryna find a new overlord with immune to frost, arrows, executions, and stealth,(reply>), @Sauron Ikov I cant. Almost everyones overlords I face have that beast slayer perk . but people dont usually pick ones with stealth defenses cuz they dont think of stealth attacks in the overlords chamber,(reply>), Or just mount a graug and spam stealth pounces
