In the Restless Canopy area of Nahantu, there is a side quest called “Overcoming Suffering” that cannot be completed if you have a mercenary. The problem is that you are supposed to sit in a chair and take damage from a small enemy that repeatedly spawns. However, your mercenary will continually one-shot this mob (on normal at least) and not allow it to hit you. You can get around this by letting everything else in the area respawn and path them to you so you can be hit while sitting in the chair. So it is technically still doable on normal with a mercenary, but it doesn’t look as if it is intended this way. There should be a command to have your mercenary stop attacking, or a way to dismiss and call back your active mercenary. I think this would fix this issue and potentially other issues/complaints people may have related to the mercenary always being active.
Yeah, little annoying^^
Mercenaries:
You can dismiss them at the Den.
Afterwards you are alone…
If you play a Spiritborn and wear the Shroud of Death chest, the enemies can’t see n hit you to fill the bar because you are in stealth after 2 secs…
So drop the chest to end this quest.
