I've seen a lot of people express the opinions that Demonic Co-Pilot and Feeding Dependency are badly costed, and it's occurred to me (particularly since Cold Days) that Sponsor Debt looks very similar in a narrative sense, but is mechanically much more interesting. With that in mind, I propose the following as a possible replacement for both of the aforementioned abilities:
Beast Within [-1]
Description:A powerful force dwells within you, offering power at a price.
Musts:You must have an aspect, usually your High Concept, explaining the nature of your supernatural partnership. This is most common among vampires and shapeshifters, but various scions may also have an inner nature which tempts them with power.
Effects:
Draw on the Beast:You may take sponsor debt instead of spending Fate Points when invoking aspects. This may usually only be done when drawing upon your supernatural powers (e.g., a hexenwolf biting someone with its Inhuman Strength, a White Court Vampire luring someone with its ability to Incite Lust), but may also be used for other activities in line with the nature of your Beast (e.g., a hexenwolf using Stealth to stalk prey, a White Court Vampire using Discipline to resist a compulsion to stop feeding). Invocations of the aspect tied to this power are always applicable.
The Price of Power:When you acquire this ability, specify an agenda for your Beast. This agenda is not necessarily malicious, but it is inhuman; shapeshifters are pulled to follow animal instincts, vampires are driven to feed, etc. The debt you incur with this power may be compelled to force you to act on this agenda; as with any sponsor debt, refusing the compel does not resolve the debt. The debt may also be compelled to deny you access to your powers for a scene (although never Creature Features).
Ever-Present Threat [+2]:For some, the Beast does not lurk quietly until drawn upon, but constantly slavers at the gates of the mind. Choose which of your supernatural powers can be aided by your Beast (at least two points of Refresh worth); the first time in a scene you use any of those powers, you incur one point of sponsor debt without the benefits of a free invocation.
