We got most of our spell structure from this unfinished fan made conversion: https://wiki.rpg.net/index.php/NWoD_Fantasy:Main_Page
We also scrounged a few low power spells from the Mage books, but some of that stuff is world-breakingly powerful.
The rest is pretty simple honestly. I took the ability list from vanilla WoD and replaced things like computers and drive with arcana and ride. We're very rp focused, which is good because I'm not super experienced in WoD combat. The crew's made it quite a few episodes already without trying to stab anyone, so we'll see what we have to do to make things work when that inevitably crops up.
Thanks for the interest! I'm enjoying the way WoD keeps most of the math out of the way for listeners so we can all focus on the story that's being made. I'd definitely recommend it for groups that value fluff over crunch.
