Void summons are free. Freespawn hybrids cost 9 or 11 gold per unit, hybrid troopers 14 and hybrid soldiers are more expensive. Mad priests, madmen otehr similar are 1 gold per unit, so every 15 cost 1 upkeep.

As an aside, Mictlan slaves cost 1, most crossbreeding foul spawns cost 1 and BF Ulm thralls cost 2.

Trolls cost 60, sea trolls 50, war trolls 80 and troll moose knights ~80. I don't have the unit DB (or Open Office, so it's a moot point) at work or I could check most of those numbers for accuracy. You'll get to see them once I get done, which won't be all that long anymore since #1-1475 are already done as are a good chunk of the remaining ones. Couple of weeks tops and the Unit DB should be ready.
