My one piece of homebrew: The Shaman. A Druid replacement with more powerlevel control.
The bargain bin- malfunctioning, missing, and broken magic items.
Spirit Barbarian: The Barbarian, with heavy elements from the Shaman. Complete up to level 17.
The Priest: A cleric reword which ran out of steam. Still a fun prestige class suitable for E6.
The Coward: Not every hero can fight.
