From publisher blurb: The Thaumaturgic Codex: Book III presents 20 unique spells for use with the 5e d20 RPG system. Some of these spells first appeared in our other OGL titles, dating back to 2003, but have been gathered here and revised, improved, and updated to the new system. Others are new and were created for this edition. A few have been gathered from our other 5e titles. Included in this collection are spells up to 9th level such as: Abyssal Vortex: Targets make three saving throws against the negative energy, acid, and mind bending power of this 9th level spell. Diaphanous Shift: Become ghostly and transparent, gaining resistance to weapon damage with this 3rd level spell. Labyrinthine Conundrum: Preoccupy your enemies with a contagious, unsolvable riddle! Salty Wounds: Inflict debilitating pain upon your injured foes! Soul Power: Bolster yourself or your allies! Gain protection from necrotic damage and bonuses on your d20 rolls! Terra Form: Become a giant, stone creature, infused with the power of the earth!
