2. Magic: Over 100 new spells for bards, druids, gnomes, illusionists, and rangers.
3. Monsters: 120 new monsters: mimics, piercers, shambling mounds, banshees, coffer corpses, terrible eyes, metallic dragons, liches, drow, deep ones, the terrifying tarrasque and many more classic Advanced era monsters! Includes complete encounter tables for dungeon levels 1–8+ and all types of wilderness terrain.
4. Treasures: 150 new magic items: the apparatus of the crab, ioun stones, the deck of many things, dancing swords, holy avengers, and many more!

Not a Standalone Game
