Switching to Abyss Lich bricks my build. (Solved)

Hi, I thought that switching to this will just switch a couple of my ascendancy nodes. But I lost all my minions.

I can't continue playing the game. Is there an easy way to revert this change without doing the trial, since it is impossible to do so without any new gear/skills, which would take new investment, which I can't farm because I lost my build. :)

If you are able to revert my character or tell me an easier way, that would be awesome.

Thank you in advance!
