The Freebie (2005)

From the designers notes:

This little booklet serves two purposes. First, it features a number of feats from Interactive Design Adventure’s Modern Advances series that are introduced in one booklet but also referenced in others. I figured it would be easier on those using these for games if those feats were put in one spot. Second, it’s a free taste of the sort of material you’ll find in Modern Advances.
But wait, there’s more! Knowing how much gamers love free stuff, I decided to include some brand-new material as well. Within these pages, you’ll also find new feats, some magic items (or FX items, just to work in a Modern OGL game term I find annoying), and a spell that’s never been seen before (except by visitors to my message
