You'll have to excuse me, Xilos. I had a response typed up last night to you that appears never to have actually been sent according to my outbox.  :-\<br/><br/>What that basically means is that for every character point you put into your summoned creature you are docked one potency. Character points are used to purchase attributes/powers/skills/etc. Your normal character has 12 starting CP. So say you wanted to summon a creature with +2 to body, a level 2 power base, and a level 2 energy blast. That would cost 6 CP and thus you would be docked 6 potency for the summoning.<br/><br/>I hope that explains it. :)
