Tips for getting skeletons to play nice with Derrin?

[Winters]

I've been spending an embarassingly long time trying to get one of the catacombs skeletons to get along with the lad. I've had Derrin stationary while gradually bringing the skeleton closer, Derrin for his part doesn't seem to mind them at all and stays completely blue until fists start flying, I got the skeleton comfortable at a distance seemingly indefinitely but up close the skeleton frequently loses their cool after 30 seconds (yes I've been timing it). This is definitely progress from the skeleton engaging on sight as they were initially, but I've been hitting the skeleton with calm at any sign of aggression for at least an hour and it doesn't seem to be getting better. I don't have Directed Trust yet, would that make a difference?

I saw some other threads on this, I could probably just go back and get a friendly zombie from upstairs, or I could shelve this until I have command dead and grab that skeleton in the tub from level 1 or 2 which sounds friendlier to start with. It's just that I was about to go through the portal and I wanted to have another more capable fighter with me at that checkpoint.

I'd thought this skeleton was simply too aggro to trespassers to be reasoned with, so I released the binding and they're currently patrolling by the ornate sword chest. However, it turns out they're 100% chill with me, just walked right by me pure blue and barely spared me a glance even without the use of spells. So, it seems there may be hope for this project yet. I'll chip away at this some more later and update if I make progress but if anyone can help me on my way I'd appreciate it.

As far as I know Direct Trust doesn't currently work, so don't bother wasting exp unlocking that.

Other than that I've seen a post where a guy explained how to make prettt mich any minion friendly with Derrin, though I haven't tried his guide because it seemed like too much work.
Cantube bothered to search for the comment right now, but you can just use the search function in the forums to find it yourself.

I locked Derrin in a room. I used the calm spell and kept running to prevent the fighting. They make following you a priority.

If Derrin helped you ‘kill’ the skeleton the first time, they might never be friends. The skeleton will remember that Derrin helped kill him, so leave Derrin out of sight while you take on the skeleton yourself.

No I don't even have command dead yet, I left Derrin behind and grabbed one using loyalty, we had no prior interactions. I read that post Blame mentioned about getting friendly undead to be chill and I was trying that method, after another half an hour of peaceful exposure the skeleton still wouldn't keep calm in close quarters. They just really seem to hate Derrin in particular, unless someone else has had better luck I'm going to say that the way you get catacomb skeletons and probably other hostile undead as a third party member is you don't.
