From publisher blurb:
Your ultimate resource for mythic spells!
Mythic Magic: Ultimate Spells I completes the mythic rules for every spell in the Pathfinder Roleplaying Ultimate Combat rulebook. All of them. If it's not already in Pathfinder Roleplaying Game Mythic Adventures, it's right here, from absorb toxicity to wreath of blades and all spells in between. Whether you're an arcane or a divine caster, Mythic Magic: Ultimate Spells I contains mythic spells of every level and every kind, from orisons and cantrips to the mightiest 9th-level magics. You will find combat spells like brow gasher, chain of perdition, and shadow bomb admixture right alongside defensive magic like bullet shield and communal spell immunity, spells to aid your allies like effortless armor and terrain bond, and utility spells like abundant ammunition and tactical acumen. They are all here, every one, developed with flair and function in mind as only Legendary Games can bring it, by the same designers that wrote most of the mythic spells in Pathfinder Roleplaying Game Mythic Adventures in the first place.
