anyone able to have Lady Druella as perminent follower?

Without the force dominication spell ?

I'm only expert in persusion now but If I would have been a master would she stay?
Swift and murgo left the party as well after their quests...

 

It's scripted, so there's really nothing you can do. You can examine the scripts and see what the conditions are for her leaving.

 

Yea I was trying to, however seeing that see did not have a level up scheme I gave up.

I my current playtrough I try to make my party as big as possible. I edited the educator background so I could bring an infinite amound of followers. However in game the limit is at 7 (excluding the free one)
Don't think that can be edited without hacking arcanum...

What I what to do now is to make every follower a free one. Is there a diffrence between free followers like twostones and dante in scripts compared to the non-free followers?
