Pathfinder Roleplaying Game: Mythic Adventures includes:
Complete rules for playing mythic characters of six different paths: archmage, champion, guardian, hierophant, marshal, and trickster.
New mythic feats for every class, such as Powerful Shape, which allows druids to transform into enormous animals, or Deadly Stroke, which lets a mythic character dispatch even a formidable enemy with a single blow.
A whole grimoire of new and supercharged spells. Bring down a castle with a mythic meteor swarm, transform the landscape with terraform, or make every memory and record of someone disappear with mythic modify memory!
Tons of monsters enhanced with mythic abilities and ready to challenge your heroes, from dragons to vampires!
A hoard of new mythic magic items and artifacts. Brandish the sword of inner fire, capable of burning even elemental creatures, or turn your enemies to stone with the medusa-headed shield aegis!
A complete mythic adventure for 7th-level characters.
Advice on running a mythic game and forging your own legends.
AND MUCH, MUCH MORE!
