Djinn
I'm working on creating a djinn. I would like this to be a blend of what is in the Quaran and the western wish granting genie that we're all familiar with. Of course, this being the Dresdenverse, I also want some scary bargaining built in.
Here's what I'm thinking:
Limited to Channeling one element outside of the Nevernever. [-??? see below]
Breath Weapon (whatever element the djinn channels). Uses Discipline. [-2]
Gaseous Form. [-3]
Wizard’s Constitution (also applying to mental consequences). [+0]
Supernatural Mental Toughness (only applies to spellcasting) granting 4 additional stress boxes. [-3]
True Shapeshifting [-4]
Within the Nevernever, may cast any thaumaturgical or evocation effect with evocation’s methods and speed. [-6, -8?]
Wishes.
The djinn may perform any thaumaturgical or evocation effect with evocation’s methods and speed when doing so in the service of a mortal.
When doing so, the djinn may add its Lore bonus to both the power and control of the spell.
Alternatively, the djinn may grant the mortal an enchanted item. The enchanted item has a number of shifts equal to twice the djinn’s Lore, which are split between uses and strength. Once all of the items uses are expended, it may not be recharged.
Finally, the mortal may use this as an excuse to spend refresh on Supernatural powers, forfeiting any bonus he receives from being a Pure Mortal.
If the djinn ever grants more than three wishes to any mortal, the djinn must serve that mortal for the remainder of the mortal’s life. If pressed into service this way, the djinn no longer receives his Lore bonus on spellcasting and may not grant enchanted items.
Djinn may refuse to grant a particular wish, but may not break a bargain once struck (such as a bargain for exactly three wishes in exchange for something on the mortal’s part).
I like, more or less, how this works. But I have no idea how to cost it. Obviously I don't intend to have the custom power that Wishes would turn into be available to players, so it's not strictly necessary to do so. I still would like to.
