Feed on Emotions (Su): An al-jahar can feed off emotional energy, but it can only feed off intelligent creature gripped by strong negative emotions (rage, lust, greed, et cetera), although such emotions can be natural or induced by such spells such as domination, fear or rage. An al-jahar can attempt to feed off all creatures within a 30 ft. radius. Any creature gripped by a hateful passion must attempt a DC X Will save, if they fail they take 1 Charisma damage and can not be affected by any al-jahar's feed on emotions attack for the next 24 hours.
Al-jahar must feed on emotions to sustain their powers. One point of Charisma damage is enough to sustain an al-jahar for a day. If an al-jahar goes hungry for more than a week it is unable to use its 1/day spell-like powers, if it goes hungry for a month its 3/day powers become 1/day powers, after 3 months it can only use its at-will powers and is fatigued, and if it goes hungry for a year it cannot use any of its spell-like or psionic powers and is exhausted (although it can still change shape and sense and feed on emotions). It is impossible for an al-jahar to starve to death, they can linger for centuries without the strength to cast a spell. An al-jahar can recover from a stage of starvation by feeding off Y [10? 5?] points of Charisma.
Upon reflection, I prefer "sense or feed" over "sense and feed" in the Feed on Emotions description. I think I'll revise it.
Plus, I am leaning towards having 5 points of Charisma feeding being enough to revive a starving al-jahar one stage.
