Those aren't stunts. There's really nothing stuntlike about them.

Why not just use Powers?

They are stronger than standard stunts, hence the reason they cost -2 Power Points instead of just -1. I am definitely overpowering the stunts, but that's my personal and groups call. These are stunt-like in the fact that they add trappings to the Crafting Skill.

Powers wouldn't work because you don't need magic to use Alchemy. If it were a power, then you would have to be magical in nature in order to use. In the world we are playing in, magic is outlawed. Hence the difference.

This is a way for my players to grab Craft Alchemy without becoming magical. It is also a way to ensure that the crafters are being useful to the group, instead of spending the majority of their time building something that'll take longer than the campaign to finish.

I'm running a Fantasy game using the Dresden Fate system. Magic exists and is quite prominant. In fact, the mortals of the world have figured out how to harness the magic through Alchemy to get Guns and Airships. One character has claimed Airship Pilot and Mechanic while another has claimed Marksmen and Weaponsmith.

My question is how do I run Craft Alchemy without making it a Power (thus removing the Pure Mortal template)? This means that Craft Alchemy has to be a stunt utilizing the existing crafting rules. Though, the existing rules don't say much beyond "you can craft mundane stuff". I have several ideas so far:

Idea 1: Craft Alchemy Stunt

This stunt would simply add a trapping to allow the mundane crafting rules to include Alchemy. Thus, only those who study alchemy can actually craft with it. However, I'm not sure how to craft a Car or a Flash Grenade (or even the rules of a flash grenade). How can I leave this openended?

Idea 2: Batman Utility Belt Stunts

Basically, take a stunt and use what you crafted as the explanation. I don't like this idea because anyone can just grab a Flash Grenade and use it. They don't need a stunt to do so.

Idea 3: Combination of the two

A suggestion I saw at this thread: http://www.jimbutcheronline.com/bb/index.php/topic,17945.15.html

After this wall of txt, I'm leaning heavily towards Idea 1. Just need to figure out the specifics.

Thanks to everyone for the awesome ideas. Definitely clears the air a bit.
