Well, I did not ask succubus treated as cohort. GM said to treat succubus as cohort and I think the whole term confuses the overall function of the spell.<br/><br/>I am fine I recast the spell if I do not need make the magic circle and dimensional anchor also (would need remake charisma check to 're-negotiate' the contract which this case favors succubus heavily with her +8 mod vs +2 mod of mine). But the point of true name was to remove the extra hassle and keep record what day succubus is about to take off (as true name possessing allows bend the normal rules of the binding to make years lasting contracts).<br/><br/>So far as I know the succubus should be long term than short term thing (unless succubus gets killed in action and with player controlling succubus it should not be case as despite binding succubus is not suicidal; it would seek survive with limits of the binding).
