That sounds more like a magic addiction mechanic (Willow in Buffy anyone)? I can see the parallel to the lawbreaker mechanic, but it is much more opt in.

Right now she's looking at trading her power for am Unmaking, but I'm open to other suggestions.  Children are not an option, nor is anything else that would impede another's free will.  But if anyone can figure something out, it's going to be this board.  Thanks!

Well, if it is a matter of free-will and children being raised by fae, there is offering up your firstborn, such that the next child you would otherwise be the parent of is simply never born...

Where are all of Ancient Mai's magically turbo-charged descendants that she rules with a fist of iron? 

I will need to do something with this as a player or GM someday (esp after the Tiger mother stories getting around the past week).

After a number of uses of Thamatergy, I still have not rolled control to cast. The interesting bits are finding a link to the target, and the prep-work. Then seeing what I can pull off with my effect.

The thing to note with Wards is that people with more Lore and Refinement [wards] can likely pull off things that Harry would have trouble with (though if I were stating up the merlin, I would give him a combat warding stunt too).

This is to true shape-shift as nounmancery is to channeling.
I'd go for the full [-4] true shape-shift off of the high concept 'animal shifter' (and however much modular ability you want to pay for). There is no discount off the cost, but, every time you'd want to shift into a hedge or a wall hanging and can't, you get a fate point instead. For that matter, every time you want to shift into another person, or a different colored dog and can't, get a fate point.

I do agree that feeding dependency seems the right thing to build off of. It also means that shifting to an easy form (not using modular abilities) is less of a strain then harder forms (with large, small or wings).

Also, good idea with the index cards.

How does one  without hurting feelings suggest to a fellow player that their character concept is pretty cool but not really Dresden Files ?
Of course they have not read the boooks and refuse to read any parts of the rulebooks.

Carefully.

"I know you have not gone through the background or read the books, so you might not realize that $concept does not really fit the genre of the game and the setting, even though it is really cool. The closest thing I can think of to what you want is $idea. What is appealing to you about $concept, I may be able to suggest something with similar features from the setting that you may not have known about."
