I started a new game but haven't even got off the starting ship, so I don't know much myself. From the feedbacks though, I'm getting the impression this new NPC is more trouble than he's worth.
I don't see any problem with making this kind of companion unkillable. In many other games like Neverwinter Nights, Skyrim, or Fallout 4, your follower is simply incapacitated when their health drops too low and they're out of combat for a while until they regain enough health. If this NPC doesn't even participate in combat, that's all the more reason.
Aside from better AI, if we're not making him straight immune to stuff, then we can just give him something like 100% HP regeneration per second or something - at least when out of combat - so it's almost impossible for him to die.
Well, unless dying is actually part of this companion's features. Like story consequences and all that.
