That and you're overlooking a major theme in the FATE system... Fate points.

The person chasing should start slinging around fate points to make declarations, tag Consequences, Invoke Aspects, Compel Aspects and create Manuevers.

The GM (or player of the Chase-e) could then start slinging Fate Points back to negate these attempts, also helping you get your players into the mood of a fluid FP Economy in game (as I find new players love to hoard their points).

Wouldn't you need to actually (if temporarily) put everyone -in- the Nevernever for them to be hurt by it? Otherwise, all that would come out, would turn to ectoplasm...

Only once the gate is closed, unless the caster is expending energy to give it form, like a summoning.
Either way, I don't see it as being an attack unto itself... but it is an awesome aspect to place on a scene for declarations and maneuvers!

How I would go about this...

1. Rent a small apartment away from my home/base of operations.
2. Fill it with all the tech I desired (Computer/HDTV/so on).
3. Have Magic Circles erected around all tech components.
4. Place permanent scrying spells around the apartment to relay sight/sound back to my actual place of residence.
5. Bribe dedicated army of pixies, with pizza, to live in the apartment and act as my "Remote Controls." Using the two-way TV scrying spell, I'd hold up "Channel 39," a pixie would change the channel and I'd be enjoying Cartoon Network. In the case of the computer, I'd have two ages old type-writers, linked through hours of thaumaturgical work so that when one types up an (email/URL/flame/etc.) the paper is ejected from the other machine, which is then transcribed by pixie onto the computer. Mouse duty (meaning the human interface device and not a rodent or large dog [as you have to be very straightforward with the Wee-Folk]) would earn the assigned pixie a double ration of pizza for that week.

Pros & Cons of this approach:
Pros:
You get to watch all the TV you want and no-one could ever change the channel on you because the pixie's would fear the loss of their pizza supply.
Internet Porn (provided you have no compunctions about the little people seeing what turns your crank. Although, in their defense, they're pretty damned open-minded about such things, you naughty wizard).
Geek/Wizard Cred - Your mortal friends (and those close enough to count to use tech without all this work) will be extremely impressed at the lengths you go to to acclimatize to the modern technological society. The wizards will be impressed because in all your dealings with the Fae Courts you are addressed by your new title...

Cons:
Your new title - "The 'Za Nerd"
Expense - Hell's Bells! Not only are you paying for a second apartment, cable television and a broadband connection... but you have to pay to feed all these pixies!
Security Deposit (you're never gonna see that money again) - Pixies are not the cleanliest of the fae on the best days, you involve pizza and your new apartment looks like the aftermath at the Battle of Helms Deep... in miniature.

Thanks for the attempt, but I know what all the terms mean.

No, I was looking for the PDF that had all the terms and definitions on it, that was making it's rounds on the forum a while back. My intent is to hand each of my players one so they have a cheat sheet to use until they get used to all the terms that get thrown around the table.

I have two nominations to throw in...

Game of the Year: The Highway to Hell (A cityless DFRPG Campaign)
Seriously... I want to be a part of this game, it's that good.

GM of the Year: AdmiralDuckSauce (GM of "The Highway to Hell" game)
This guy seems to work really hard at making the game as enjoyable as possible for all of his players. Has his plans laid-out, including soundtrack, but is willing to let it all go to hell for a well-spent fate point "that could make it MORE AWESOME."

I invite you all to read for yourself http://www.jimbutcheronline.com/bb/index.php/topic,21813.0.html

My Dresden Files character had something along these lines. It was a chain (tungsten/platinum allow that acted as his staff) with a clip at one end, when used in conjunction with Thaumaturgy it gave him +1 shifts for spell preparation (in the rules it had a +1 Thaumaturgic Control bonus, assigned as a focus item).

He couldn't keep an active circle while walking about of-course... but he always had the benefits of a well crafted summoning/magic circle on hand.

Also I wanted to note that Magic/Summoning Circles tend to create cylinders, not domes, as stated here...

A magic circle is interrupted by any physical object crossing its dome-shaped barrier. So merely trying to wear one on your head would interrupt it; your body would be crossing it, not to mention anything above and below you moving in relation to the circle.

Absolutely bad-assed. I had to laugh at one point, because I've put the consequence "Don't Taze me, Bro" on an NPC in my game. I have to say, your Highway Hellions have some rather epic adventures and again... I can't wait for the next installment!
