I was playing Soul-Gate as ermor, and I set all dominion stuff, related to living, to sloth-3, chaos-3, death-3, luck to 0, and magic to +3, then I decked out my lich queen with level 3 nature, 3 fire, 7 death, and 7 astral. I got to the point of casting Wish around turn 50, so I got the idea to summon Bargraphal or however you spell the worm-looking demonlord, several times. Then I used Gift of Reason to make him a super trooper.
I was wondering, shouldn't there be a limmit to them though? Since there are only three... or did I just clone a demon, incurring the wrath of the underworld.
