What refresh level are you playing at? If its a submerged game I have a possible solution for you, the powers for my red court vampire character (yes, a full red court vampire):
Gifted With Soul [+1]
Description: You are different from other Red Court Vampires. Normally your kind do not have a soul, for it is antithesis to your being, and destroyed once you have had your first killing feed. You however have somehow managed to store your soul in an item, making a phylactery of sorts.
Musts: You must be a red court vampire, must have an aspect that reflects this power.
Effects:
Silence the Beast. You loose your Echoes of the Beast power. As a Red Court Vampire with a Soul your beast is suppressed by the morals other Red Court Vampires lack.
Refresh Bonus. You have somehow maintained your soul, keeping free will. Add +1 to your refresh level.
Phylactery. Your soul is stored in an item that you must keep on your person at all times. If it leaves your person, you loose the above benefits, becoming an NPC. You may spend one fate point to give you one days time to retrieve the item.
Altered Catch. You are no longer burnt to a cinder in sunlight, but you are weakened in it. In sunlight your catch is automatically satisfied for any attack. In addition add a new condition to your catch: "Phylactery Damage."
Made Whole [-1]. If you take this upgrade your soul no longer resides in your phylactery, which becomes a mundane item, it has been restored to your body. You loose the "Phylactery" portion of this ability, and the "Phylactery Damage" condition on your catch.
And here is the next power my vampire will take, once she gets the chance:
Fountainhead of Blood [–2]
Description: You've somehow managed to cut the metaphysical ties that exist between master and servant. You are no longer beholden to the Red King, and are a sovereign in your own right.
Musts: When you gain this power, you must change your High Concept to reflect your new status as the fountainhead of a new bloodline of red court vampires.
Skills Affected: Discipline, Social Skills.
Effects:
Self Control. Your control over the thirst is unparalleled, you gain +1 to your Discipline when using it defensively.
Deeper Reserves. You are the most powerful vampire in your bloodline. Add two boxes to the length of your hunger stress track.
Liege Lord. You are the fountainhead of a new bloodline of red court vampires. Any social skills used against other vampire courts or bloodlines gain a +1 bonus. Increase this to +2 when dealing with members of your own bloodline.
Improved Feeding [-1]. If you purchase this upgrade you gain a +2 (instead of a +1) on subsequent attacks after causing your enemy to bleed, in a grapple you do two extra stress instead of just one. You may also use the Taste of Death of effect of the Blood Drinker power twice per scene instead of only once, however you must spend a fate point to use it the second time.
