Any tips on who I could kill and summon as my thralls? Currently I'm looking around for two other mages who can summon so I can effectively have myself, my mage follower (who can summon), and two other dead mages (who can also summon) giving me SEVEN in a party who will fight alongside me (I play on the PC so I can just use the tcl command in case they get in my way / block a path)!

Any other good ones I should try using the dead thrall spell on?

Thanks.

I wonder if you could make those boss Dragon priests your thrall...
