Desecrated ground is ridiculous

I just got to the endgame and started doing maps and it's overall a smooth sailing with ranger, but a had one of these abyssal rares spawn on a map and whenever it got close to me my HP would drain to 0 in 2 seconds. It would happen so fast I had no idea what was even happening. I died to this mob every single time until I ran out of map entries, but realized I could pause the game and still read the status effect in the UI and it said it was "Desecrated ground". This effect is the most broken thing you ever came up with, I don't know what the point is, literally drains HP to 0 in 2 seconds and you can't even regen at all. The mob also had life regeneration and shroud walker so it kept teleporting to me and immediately killing me with this stupid effect and if I ran off it would regen. This is the dumbest thing ever and it was literally impossible to deal with it in any way.
