It is HUGE but Fate love is quite well represented there.  Of course, there are a fair amount of detractors.  Sucks this forum is going away. My 7 year DFRPG/DFA game was started here.

Mine began here too, and I still come here for advice and help. Gonna be a shame to see it all go

Thanks everyone for the posts, ideas, and help

So, based on suggestions, here's the revised Child of the Armageddon Template

Child of the Armageddon
A Child of the Armageddon is one who carries the taint of Darkness (be it demons, Outsiders, Hell, etc) within their blood. This taint is passed down through the generations from parent to child. This taint endows the Child with an extraordinary power, however, the ability to absorb the power(s) of any Supernatural Being touched.

Musts
High Concept Must include your tainted nature (ex: Child of the Armageddon Detective, or Demon Tainted Cop)

Powers:
(-Varies) Mimic Abilities (note, as a Child is not a shapeshifter, they suffer a hunger track similar to that of a Vampire (as noted below). )
(+1) Feeding Dependency (Powers):  At the end of a scene where a Child takes the powers and/or skills of another, or uses already acquired powers, they suffer an attack equal to the number of refresh taken, resisted by their discipline.

Important Skills: None
Minimum Refresh Cost (-Varies)
From the Casefiles: Shannara Chronicles Season 2

So, came up with two concepts for a campaign concept I am working on, and want opinion/suggestions on the from the community. Thanks

Instead of a loss of powers, however, failure to deal with any stress overflow results in 1 free compel on the character per stress not absorbed.

Fiction
A fiction is exactly what is sounds like, a being formed from the imagination of a mortal. In reality, a fiction is actually a Spirit being, that has manifested a physical form based on inspiration drawn from a mortal mind. However, once the form is taken, the Being is, for all intents and purposes, the fictional character who the Spirit appears to be (ex: A Fiction of Captain James T. Kirk, IS Captain James T. Kirk physically and mentally). The Fiction does retain knowledge of who it truly is, but they will not admit this to anyone, though they do go out of their 3way to fit in (meaning Captain Kirk will blend in, not run around asking where his starship is, or shooting random people with his phaser.) While fictions can be beings out of fantasy (Halflings, dragons, etc) the spirits involved tend to prefer modern and science fiction beings to become.

Musts
High Concept Must include fictional nature (ex: Fiction Security Guard or Fiction Soldier)

Powers:
All powers are based on the character the fiction is, with the exceptions below. Most powers will manifest as Objects of Power (with only the first one getting the refund as per the rules)
Human Form (+1)
Swift Transition with No Mortal Home (-1)

Important Skills: None

After re-reading the sections in the books about refresh, I'm going to go with refresh every session, unless the session ends in the middle of a combat, whereupon the refresh will occur once that combat is completed

I should point out that only one player at this time will be using the deck. The rest seem to be sticking to the dice

Well, there are, as so often, a few ways to do this.

First, the Aquatic power seems like a must.

As a base concept, I think we could take something like this:


High concept: Cursed Mermaid
Trouble: Cursed to [insert effect of curse]

Powers:
Glamor [-2]
Human Form (Involuntary, touching water) [+2]
affecting:
 Aquatic [-1]
 Inhuman Speed (representing the fin) [-2]

Total cost: -3

This would be your mermaid who would get legs when she is on dry land and a fin when in the water. That would make it easier for her to be useful in a campaign. The involuntary part of the human form can underline the curse.

The curse itself would make most sense as your trouble aspect. It would be compelled when the curse acts up and bad things would happen to you. In return, you would get a Fate point.

If you want to have more powers (for example greater glamors instead of normal glamors), you'd just need to adjust for that. Or we could look into other powers. Commanding fish, for example. Or anything else you like her to have.

Oh, I'm not really using a template here. You could probably fit this into the changeling template, but I find they are good as guidelines but can get in the way with some characters. They are better created freely.

I am SO stealing this as a template for my DFRPG Campaign world. Of course, credit will be given where due

Rejected here as well
