Changeling the Lost is my favourite WOD game, though I use a highly hacked version to present more diversity amongst the True Fae i.e. more benevolent members and to amp up the urban fantasy feel. However, I love DFRPG and love it's portrayal of magic users i.e. wizards, focused practitioners, hedge-witches (custom template I made for middle ground spellcasters) and minor talents, well over Mage-pretty-much-a-god the awakening.

Do you think DFRPG could handle Changeling the Lost with Pledges, Contracts, Talecrafting, Hedgespinning etc. or is Changeling the Lost to complex for FATE?

Immunity to Power really should only be taken for powers that can actually effect other things, and not just yourself. In my setting its mostly to reflect the fact that Iron cannot be affected by any Faerie Magic, be it seelie/unseelie magic or Glamours. But it also affects some other powers. For example Incite Emotion used by a Raith WCV who take this frailty would be able to affect people who are truly in love with much less affect, a -2 to the rolls to be exact. To be honest the fact that physical immunity includes a -2 to all rolls when using or maintaining the powers effected by your Frailty when used against those carrying the Frailty is in my opinion worth another refresh point.

In my setting all Fae have a feeding dependency. To be honest i picked the end of a scene as a place-holder. May i ask what you would believe is better? I am really open to suggestions :-)

Just a quick question to the forum. In my game Fae are far more susceptible to Iron than presented in the books. Not only does it harm them, but their magic cannot effect Iron in any way. Likewise its very touch weakens them and makes it more difficult to maintain a Veil or Glamour.  I am trying to figure out a way to express this within the game. I am thinking of adding it into the Catch, but am unsure how to price it. Any help would be greatly appreciated 

That's true for Changelings, but not scions.  All Changelings are scions but not all scions are Changelings.  Each type of scion is its own "type" while some might face a choice, or type of choice, I'd say that not all (and maybe not most) do.

Techinally if we are going by cannon, In one of the WOJ, jim butcher said that scions have to make a choice as well, just like changelings. I can't it at the moment, i know it was one of the more recent ones, as it was a question he was asked post GS

Your right, there isn't any specific concering if they are made of ectoplasm, so i guess until we know for sure it will always be conjecture either way. On the note though about how lea could have entered the threshold of harry's apartment, i was rereading the short story something borrowed today, and jenny greenteeth was able to enter the threshold of georgia and billy's apartment to kidnap georgia. And within the same story, harry comments on how their apartment has a very strong threshold. From this i can only interpret that the Fae are able to enter threshold's, but most likely lose a large portion of their power like wizards do (jenny physically attacked georgia rather than use magic on her which seems to support that she lost most of her magical oomph when she entered the threshold).

Well the erlking in itself is a touch confusing, i mean one wouldn't really class him as a court of his own since according to WOJ he is a king of summer.

I actually came up with a template that matches your character perfectly on another thread. Btw i allow characters who take this template to take more than one refinement if they wish, but doing so they can never take Evocation. So its a choice either learn Evocation some day by advancing to a Sorcerer or Wizard or focus completely on Thaumaturaphy and become a more powerful Hedge Witch or Hedge Wizard.

I created this template because I felt there was something missing in the low level spell casters Templates. I felt that while the Focused Practitioner is well and good for some low level practitioners, it neglected to show those who have more well rounded mystical portfolio, but lack the ability to use evocation or Channeling.

Hedge Witches and Hedge Wizards are quite skilled at numerous spells and areas of magic, but they take time to actually cast their spells. This is reflected in their ability to use Thaumaturgy just like Wizards or Sorcerers but they lack the power or skill to actually wield Evocations.
Many Hedge Witches and Hedge Wizards colour their magic and spells with some alternative religious feel, being that many are also Wiccans, New Age believers, practitioners of religions like Sanitaria or Voodoo etc. This means that for them to cast their spells they need the trappings of their faith and their beliefs, for example most Wiccans have an altar which they practice their magic, including statues of various deities and other magical trappings like a pentacle, Athame, incense etc.

Musts: A Hedge Witch or Hedge Wizard must take a High Concept that declares his or her nature as a Hedge Witch or Hedge Wizard, such as MEMBER OF THE ORDO LEBES or SOCCER MUM/WITCH. In addition the Character must take the following supernatural power:

Thaumaturgy [–3] (YS page 181)

See the power description for more details.

Options: Hedge Witches/Wizards may take the Sight (-1) which would function the same as for Wizards and Sorcerers, but this is rare. In addition, they may take Refinement (-1), once per play. It should be noted that they can never take Evocation, if they want to purchase Evocation they must upgrade to Wizard or Sorcerer.

Important Skills: Conviction (YS page 124), Discipline (YS page 127), Lore (YS page 134).

Minimum Refresh Cost: -3

From the Casefiles: Kim Delaney (OW130). Also Anna Ash, (OW103), simply replaces Rituals with Thaumaturgy and raises her refresh to -3. In addition Charity Carpenter when she was younger was a Hedge Witch.
