I think he did because remember he already used shadow exchange to get to the dungeon like 5 minutes before they went in.
Make sense... （￣へ￣）
He made Kaisel a shadow in chapter 88. I think I'm confused on what your confused about
In the novel he summons Kaisel too, bu if I remember correctly, it's only after he gets out of the dungeon.
I missed something so thank u

I've read the LN and all of this as well ut I still don't remember him summoning Kaisel
