which coautl does c'tis get?

[Carkaton]

I was looking in the dom db and saw there were 2 different kinds of coautls, one with n3s3, the other with s3n1 an?2 with a 10% asn. I've only been able to summon 2 so far and they both turned out to be the n3s3 kinds, but I was wondering if they could get both kinds, or if one is Mictlan's.

Also is there a practice mod that starts a guy with insane research and gem income so I don't have to trudge through a single player game to test high level spells out?
