I'd go with Richard on this one.  Mab calls Thomas "mortal" (in respect to love), so it goes back to the man v. monster debate (the whole point of refresh)- Lawbreaker would bring him closer to monsterhood, and his refresh approaches that as well.

Mab said he's mortal enough to be the Winter Knight because he can love, and that was good enough for her. Who knows how that would imbalance things for the Winter/Summer War.

Here's an interesting question: Say, Marcone hires a mortal wizard who has no problem breaking the Laws of Magic. Would the White Council invite an act of War by trying to enforce their own laws on a Signatory of the Accords, or do you think that would fall to the Blackstaff to deal with?

Rename Han Shot First.

Where is my Like button? Damnit, I'm not on Facebook.

option 1: Gunslinger [-1]; Your ability to draw and shoot from the hip accurately are legendary; With a one-handed and holstered handgun you gain +2 to your initiative for the first round of combat and +2 to your attack roll. In subsequent rounds this drops to +1 Initiative and +1 to your attack.

option 2: Gunslinger [-1]; Your ability to draw and shoot from the hip accurately are legendary; With a one-handed and holstered handgun you gain +2 to your initiative for the first round of combat. In subsequent rounds this is replaced by a +2 to your attack.

Trick-Shot Artist[-1]; Your ability to perform incredible feats of shooting is more than legendary; You may use Guns to perform Maneuvers or Declarations that place Aspects on a target and in addition you gain +2 to Guns for the purpose of such maneuvers.

Options 1 and 2 are OP when you consider the rules for Mortal Stunts starting on YS148. It's almost like you're combining two Mortal Stunts together for the full benefit instead of using the rules for combining stunts to get half benefit.

Here are a few examples what trappings can do that seem to be in the same vein you're looking to go:
Give a +1 to attack, improving accuracy under a specific circumstance. (Example: Target-Rich Environment)

Give a +2 to an attack's result, applied only if the attack was successful, under particular conditions (Example: Lethal Weapon)

Combine any two of the 2-shift effects from above at half value (Example: Scene of the Crime)

Get a more powerful effect, but only when you spend a fate point and usually only allowed once per scene (Example: Killer Blow)

I would rework Gunslinger like this:

Gunslinger [-1]; Your ability to draw and shoot from the hip accurately are legendary; With a one-handed and holstered handgun you gain +2 to your initiative for the first round of combat.

Also, there is a Trick Shot Artist (Guns) trapping that Marcone has on OW189. Here it is.

Trick Shot Artist (Guns): When attacking with Guns, +2 on the roll for shots taken at things (not characters), such as ropes holding chandeliers, etc. (Particularly effective when used with Taking Aim).

We're not talking about the White Council's laws, we're asking if he should get the Lawbreaker stunt.

I'm pretty sure one begets the other, but I'm going with no. He's not mortal and not subject to the laws of the White Council (although the Evil Eye Cult he supplied the ritual with would be subject to those Laws and Lawbreaker stunts, which I believe they gave Madge Shelley). I also agree with Koffeykid's reasoning as it is also my own understanding of the source material. Rituals such as what Lord Raith and the Evil Eye Cult did are similar to magic vending machines. You put in the offering and the intent and in return get the power. That's the reason the White Council tries to publish new rituals, since it makes it harder on the being supplying the power and you end up getting weaker results or no results at all.

Side Note: In Back Up, since Lara and Thomas are Venators, do you think that Lord Raith may have used knowledge gleaned through that connection to get his ritual and maybe even his anti-magic shield that seems to be supplied by He Who Walks Behind?

I've only been on the forums for a few short weeks, but there are three posters that I've found the most helpful when constructing my game. I vote for:

From the suggestions so far, I'm getting the feeling that your campaign is set in Chicago.

I would suggest this is a great time to introduce new power players that will probably come into play later on.

RC - Ariana is good, although I'd personally branch out. Since it's an advancement function, you'll certainly need someone higher up the food chain, since the way I understand it, the newly advanced needs to feed on blood from a higher up.
WC - You'll probably need a head of a local house or one of their heirs. Maybe even a daughter of the King.
BC - If there are any in the region and have ties to the RC like Mavra did with Bianca, I'd throw them in just for the creepy factor.
JC - A lower functionary. I don't imagine JC has much of a power base in the States.
Fae (Summer/Winter/Spring/Autumn as applicable) - A Sidhe or a Knight. Maybe even one of the Ladies
White Council - Since at 7 months before Changes the war is still in full effect, I would probably skip this one
Freeholding Lords - Any of the Freeholding lords you want to introduce into your campaign. By Freeholding, I mean Drakul, Marcone, etc.
The other Gods - Representatives of Vadderung, Ra, Shiva, etc. Maybe one or two forgotten gods similar to how they did things in American Gods.
Denarian - If you can work up a reason why one would be there, go for it. They seem to be the type who would only go if it suited their goals to do so.

As a maneuver, my real quick now is: Would you tag this for effect or would you tag this for a +2 to a social roll. My thinking is that if the maneuver hits, the effect is already there.

Yeah, obviously the spell won't effect everybody. There is a pretty big subsection of big nasty creatures this spell would be useless against, but I think it's a pretty fun and innovative way to use a spell to create a social attack on the people it will effect.
