Quick question, from reading the Spiritual Parasitism and Corrupting Influence sections, it appears that the parasite does not gain control of the body upon entering it, and has to wait until the end of the current scene (and the ensuing control conflict) in order to actually gain dominance, after which he is only able to inflict a compel or change one of the characters aspects. Is this intentional? If not it might be worth a note in the Spiritual Parasitism stating that upon successfully possessing a body, the parasite gains control.

PS: Does anybody have an idea for a name for the first possession Power I posted?

How about 'Spiritual Symbiote', as used in the flavor text. If not here are a few others:

Shared Consciousness
Mental Parasite
Mental Transference
Empathic Insinuation
Mental Concordance
Metaconcert
Spiritual Link
Spiritual Enjoinment
Composite Mind

People can get quite touchy about their Aspects. Also, they may have been planning to do something else with their minor milestone.

Maybe instead of replacing an aspect, the taken out consequence could add an additional sticky aspect relating to the spirit's attempts to gain control, one that persists until the next milestone?

ENTHRALLMENT [-2]
Description: You can control minds. It's not quick or easy, but it's effective.
Skills Affected: Discipline.
Effects:
Domination. You may engage a willing or helpless target in a mental conflict. Discipline is used to attack and to defend. You automatically win initiative. If you are taken out, the conflict ends and you may not resume it for twenty four hours. Each exchange in this conflict takes roughly half an hour by default. You can rush this, but you'll suffer a penalty to all rolls in the rushed exchange. This penalty is -1 for a five minute exchange, -2 for a one minute one, and -3 for a combat-time exchange.
Enthrallment. If you take your target out, you may turn them into a rough thrall or into a Renfield. A rough thrall is identical to the character it once was, except that it now obeys you robotically and takes no initiative. Change its High Concept to reflect that. A rough thrall can recover given roughly a month without re-enthrallment, the help of a wizard or therapist, or a Compel against you on one of its aspects triggered by an attempt to force it to do something diametrically opposed to its nature. A Renfield is similar to a rough thrall, but retains none of its previous memories or identity. Renfields are incurable.
Superior Enthrallment [-1]. Your Enthrallment attacks inflict two additional stress. In addition, you may transform defeated targets into fine thralls. A fine thrall is identical to the character it once was, except it now seeks the goals you assign for it in place of its own. Change its High Concept to reflect that. You may also transform thralls into supernatural beings. Select four Refresh of Powers and stunts. Whenever you enthrall a character, you may grant them those abilities. Change their Aspects to reflect their new nature, as normal.

For rough thralls how would becoming one effect a supernaturally gifted being? Would a person with enthrallment be able to dominate a powerful magic user, turn them into a Rough Thrall and have them use their magic (or *shudder* have them use up their Death Curse), or would these abilities become unavailable whilst they are enthralled (you mention that Renfields lose their previous memories and abilities - which seems to imply that Rough Thralls retain them).

For that matter can this power be used to dominate an entirely non-human entity? Looking at things as they currently stand, with a little luck, a character specced out for this power could turn Maeve or Mavra into a Rough Thrall or Renfield relatively easily, something that just doesn't sit well with me. (In fact - looking at OW, Maeve would probably be easier to enthrall than Mavra...which seems a little odd)

The potential blowback from suborning the power of the Winter Lady could be very amusing and might be considered adequate motivation not to do this.

Looks pretty good, couple of points though.

From reading the synopsis it looks like Spiritual Power is adding 1 to the ranking of the skill rather than 1 to the result of the roll, is this intentional? (not sure this would really make a difference - but it seems to be what it implies).

I'd add in something about specifying whether the Spiritual Power effect is invoked before or after the roll is made (it would be much more effective if applied after the roll, but thematically one would likely call upon the powers of your possessing spirit prior to attempting an action).

The last worry I have is the  "stress and consequences taken from this attack do not begin to heal until you go a full session without using Spiritual Power" bit. Thematically I can see this working nicely, but separating out 'Spiritual Power' stress and consequences and those applied normally adds additional book-keeping to the power that is probably unnecessary.
How about if consequences are deducted as normal but the character has a additional stress track, "Spiritual Stress" where the relevant stress is applied, and which operates in a similar way to hunger stress?

an easy method is to have them start as the suspects.   

I so want to build a 'Usual Suspects in the Dresdenverse' scenario now.

Nice. Good to know I seem to understand the way the system works. How would you handle the PC making one of the 'temporary' power permanent? Like permanently accepting that much loss of his mortality/soul/freewill (not sure how to phrase this - in the books, it's the character's literal soul he's giving up, but I'm not sure how to adapt this to the DV). So, the PC is no longer drawing on Sponsor Debt, but the power is still tied to the demon - spending a Refresh point, but gaining a worsening of the 'possessed' aspect? Or perhaps a negotiation of a 'Standing' point of Debt?

As a characters remaining refresh post character-gen is supposed to represent his free will, I would allow a PC to convert a temporary power into a permanent power relatively easy. Just allow a 1 to 1 conversion of debt to refresh. Wiping the relevant power (and related debt) from the sponsor's record in return for the greater loss of a portion of his/her soul.

Hello all,

I was just wondering what you all think are the limitations of the Glamours power?  A friend of mine is new to the game, and is planning a character with it, and I was concerned about how it works?

It seems to me that the power just changes the appearance of something, without changing its function and allows Veils?

1) So could he use it to disguise himself to look like a specific person, or does it just let him look different than his normal appearance?

2) Monopoly money to real money?  Would this allow you to roll Deceit/Discipline rather than Resources when trying to buy something?  Or would that take a stunt that requires the Glamours power?

3) How would it effect things like a metal detector at the court house, for instance?

As I recall Glamours allows the PC to create ectoplasmic based illusions, which would mean the the illusions are physically 'real', ie. If your 5' tall skinny Changling Glamoured himself into an image of a 6' 6" 'Roided out Weightlifter, then to a cursory check the height and mass would be real, they'd even have an appropriately increased weight if someone decided to weigh them, but the mass isn't actually real matter, it won't last past sun-up and could probably be interfered with by magic.

1) I'd allow the PC to look like a specific person. If this was a person they were unfamiliar with (for example a random person they met on the street or a person they saw on TV or in a photo) I might impose some form of penalty or increase the difficulty of maintaining the persona.

2) I'd definitely allow the conversion of Monopoly money to real money, maybe even the wholesale creation of "Fairy-Gold" banknotes, however see above on their dispersion upon sun-up. Added to which there are numerous anti-forgery techniques that Governments embed into their currency and I wouldn't expect a glamoured note to be able to encompass them all. Cue intrusive investigation on behalf of the Federal Authorities. (On the other hand if the character had the "Document Forging" Deceit stunt and a high Burglary or Craftsmanship skill I'd probably go more easy on this).

3) I don't think it would effect a metal detector at all, even if you cover your sword in a glamour, making it look like cane or walking stick, it's still made of metal, and the detector will react as expected. An interesting occurrence would be where the material of the illusion is the same and the illusion simply makes it appear different, a compact submachine gun covered with an illusion of a high-tech TV studio camera perhaps. If this item passed through an X-Ray machine (and the machine wasn't Hexed through exposure to active magic), then would the machine see through the illusion, or would the illusionary material behave the same as real material. Personally I'd leave this up to GM Fiat.
