Core Spells
This 100-page rules supplement expands mythic spellcasting with more than 400 mythic and augmented mythic versions of core spells, ranging from cantrips and orisons to 9th-level spells. It includes complete spell lists for bards, clerics, druids, paladins, rangers, sorcerers, and wizards, along with cleric domain spells and sorcerer bloodline spells. Several new mythic feats and path abilities help characters use these expanded options. Indexed and hyperlinked references connect spell lists to individual entries for easier use in play.
