Well, a standard ifrit (which I posted before) is summonable by summon elemental spell. So I would think free ally is 1 dot and it is 1 dot cost for standard ifrit likely. So with 2 dots already in ally background should give a 3 dot ally.<br/><br/>But you can check in detail abilities and stats what ifrit has and then judge how many dots it costs to have normal ifrit and then 'prince' status ifrit (which should be significantly more stronger than standard ifrit with additional god powers).
