Believe it or not, I actually am working on Beyond the Deadly Desert (And I'll have a special announcement in that regard in a few days).
One of the things I'm wrangling with is letting players take on the role of inventors like Smith & Tinker, the duo who crafted Tik-Tok. The options that I'm thinking of are:
1) A character who has purchased the Craftsman trait can make wonders given sufficient time and effort.
2) A character who has purchased the Craftsman trait can make wonders by following the basic procedures for making magic items (gather exotic ingredients/spend Oz Points).
3) A character must purchase the Craftsman trait as well as an additional 1-point trait in order to make wonders using the rules for making magic items.
The big question is: How rare are such geniuses? Was Mr. Tinker simply specialized in a different way than Ku-Klip the Tinsmith, did he have access to better materials, or did he have a much greater understanding of his craft?
What do you think?
