From Introduction:
This supplement started life on June 19, 2011 as a spell posted in the Workshop Thread on the Dragonsfoot Forums. The first spell posted was Lighten Load (not my best work, but I've included it from a sense of sentimentality). I would probably never have taken the next step, pulling together a compilation, if winemaker81 (Bryan) hadn't put the concept in front of me. In many ways, he deserves a lot, if not most, of the credit for this. I had no idea at that time that a single spell was going to lead to the crafting of over 150 spells.
As I tinkered with spell design, I got caught up in a few other projects, some of which led to the creation of new spells (such as the Juiblexian spells, the spells of the Thorn Queen, etc.).
Not everything here has previously seen print or an audience; while a compilation is useful, I personally find that they lack the cachet that new work has.
