From publisher blurb:
H.P. Lovecraft invented the Necronomicon. Dungeons & Dragons had its Unearthed Arcana, and the Pathfinder RPG raised the bar with Ultimate Magic. No matter how you slice it, magic is at the heart of fantasy. Nothing says magic like a massive tome of spells.
That's exactly what we're compiling here. A tome of every awesome incantation, spell, cantrip, and glamer derived from seven years of Kobold Press publishing — more than 500 new and compiled spells by the best in the business, including Paizo staffers and A-list freelancers. And we're adding a lot more to that list: variant magical systems, real scrolls for amazing props, and yes, even more new spells.
This project is not just for wizards and sorcerers. Deep Magic is going to expand the horizons of what's possible for wizards, sorcerers, clerics, and oracles with something new for every casting class, from adept to anti-paladin, and from bard to summoner!
