From publisher blurb:
Uncover Forgotten Arcane Lore!
Everyone knows that knowledge is power, and that having options is better than not having them. It should come as no surprise, then, that wizards, witches, and other powerful spellcasters are always on the lookout for new and exciting spells to add to their repertoires. While many spells from the Pathfinder Roleplaying Game Core Rulebook received a facelift and an upgrade in Pathfinder Roleplaying Game: Mythic Adventures, the sourcebook that introduced mythic power to the Pathfinder Roleplaying Game, dozens of spells were left behind. Missing Mythic Magic Volume XX, and its predecessors, aim to give each and every spell from the core rules a full-fledged mythic upgrade, all the way from A to Z, with a special focus on making mythic spells that feel as over-the-top and larger-than-life as possible.
This installment includes 33 mythic spells, from stone to flesh to sympathy. A mythic summon instrument can summon entire orchestras of instruments that play themselves, or even wondrous items that are instruments. Mythic summon monster and summon nature’s ally spells allow you to grant mythic abilities and uses of mythic power to summoned creatures, while mythic symbol spells can all be recharged and made semi-permanent, in addition to other unique enhancements for each such spell, and a mythic sympathetic vibration can level even sturdy structures instantaneously. This tome contains all that, and much, much more!
