In The Company of Treants
This fantasy roleplaying supplement supports campaigns centered on treant characters, from young near-saplings to towering forest guardians. It presents treant lore, three new races, alternate racial options, aging and physical guidelines, equipment, feats, magical items, and artifacts. Twelve racial archetypes adapt classes such as barbarian, cleric, druid, fighter, ranger, rogue, and wizard to treant abilities, while the tree shepherd provides a dedicated racial paragon class and the weald warrior offers a class for creating treant NPCs. Additional rules cover plant allies, forest-based abilities, treant-specific mysteries, bloodlines, curses, and combat styles.
