This is cross-posted from my other blog.
Working on the Sigils extra was like clearing a logjam: I was able to get a strong start on adapting Synthesis to Fate Core. I realize the common wisdom with creating Fate Core settings is “start with the skill list!”, but in this case I felt starting from the other end was better. By working my way through the other Tribe 8 specific skills (Dreaming, Ritual, Sundering, Technosmithing) I’ll have a much clearer vision of how to prune and shape the default skill list.
The direction I am going with Synthesis was something that the way Fate Core is written, and how various things are categorized, really brought into focus. The four actions provide a good framework for taming a freeform beast like Synthesis without having to delve into a lot of niggling little rules and modifiers. It helped me realize (for example) that bonuses for trances, extra time, ritual implements, etc. weren’t a static thing but should be the result of the character doing something to create an advantage for themselves. The same thing will go for resisting effects; it’s not automatic, the character needs to actually do something to get the bonus. Once again, Rob Donoghue’s channeling “hack” helped tremendously in helping the rest of the pieces fall into place.
You can get the draft from Google Docs, and I will post regular updates as I tweak and refine it.
