Dominance
Dominance is a measure of your ability to will others to follow your orders. It comes into play when controlling minions such as outsiders and undead.
Your Dominance score is equal to your level. This may be modified by feats, equipment, or conditions.
The Dominance cost to dominate a given minion is equal to the minion's level. If their cost exceeds the Dominance you have, you cannot dominate them.
You are allowed to dominate multiple minions. For instance, if your Dominance is 10, you could command one 10 Dominance minion, or five 2 Dominance minions.
This system describes minions that a permanently dominated, where they take your orders without question, requiring no concentration or active upkeep. Spells and other powers that compel creatures, typically involving saving throws, do not interact with the Dominance system unless otherwise specified.
