I developed a new setting for my own system, but not everyone wants to play my new system as they'd rather stick to the familar.
However, in my new setting, magic is everywhere. Even farmers have a family grimoire of basic magic to use around the farm. PC spellcasters would simply be those with exceptional magical skill and knowledge. Further, magic isn't as limited in terms of how often it can be used.
Obviouly, certain alterations need to be made to spells, such as reducing spell damage.
In the system this setting was developed for, a spell's power was rolled against fatigue, failure would reduce fatigue. Once fatigue reached reached zero, the caster would fall unconcious. Thus low power spells could be cast all day long, while very powerful spells could quickly deplete a caster.
In the empire, there are schools for children, and magic is part of the basic curriculum.
I'm looking for ways to bring d20 rules to this type of magical world without rewriting absolutely everything (which would defeat the point of trying to make it work with d20).
Certain spells would be restricted or changed. Healing spells require knowledge in medicine, teleport doesn't involve planes, and summoning requires a sprite and a body to attach it to (hence undead, much easier than creating a magical body for this sprite to control), etc. Most of those are generally flavor and at most might shuffle the spell lvl.
Consider looking at Spheres of Power. It's specifically designed to be a system for flavoring your own magic system.
Umm, what is it, and where can I find? Please. :)
I've not heard of them.
I'll have to find some way to open the preview (phone doesn't open zips), but the sales text makes it sound like a completely new set of mechanics, which defeats the purpose of what I'm going for.
I'll post an update once I view the preview (I will not be buying however, as I really don't have the money to spend. I wouldn't have a phone if it wasn't a job requirement.)
If you can find it Green Ronin did a setting for The Black Company for 3.0, the magic system they built sounds alot like what you describe, just mske the dabbler feat common, or free.
