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 XVIII, 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 23 mythic spells, from sculpt sound to slay living. A mythic secure shelter is not only larger, more comfortable, and far more secure, but can also be made to grow legs and move about at the caster’s command. A mythic sepia snake sigil is far more persistent than the non-mythic version, and can be used to also poison the victim, to be reusable after being triggered, or even to hold victims in suspended animation indefinitely. Mythic shadow conjuration and shadow evocation can replicate the effects of mythic spells (even if you don’t know the mythic versions of those spells), while mythic shrink item can miniaturize even entire buildings and other structures, shrinking all the creatures inside along with them. This tome contains all that, and much, much more!
