For about a year and a half, my Saturday night group has been playing a Low Fantasy Gaming campaign — the longest-running campaign this group has had! Steve Grodzicki generously makes the core rules available for free.
He also has a compatibility license that allows others to publish supplements to support his game, and I have a magic-user who has been exploring ritual magic. I’ve always liked quirky magic, and I’ve been scribbling down sample rituals that I might make use of.
When Steve saw them, his reaction encouraged me to pursue the matter further.
I’m thinking of another in this line of supplements, to do specifically with creating true magic items. Perhaps Wonders of Low Fantasy.
