The LORE pages for the Champion classes are incorrect and missing required information. All Champions and Unholy Champions must be the same alignment as their deities. This is CE for Corath and Pyrtechon, LG for Vorax and Toran, as opposed to "Any evil" and "Any non-evil." All Champions and Unholy Champions must have Weapon Focus in their deities' favored weapons.
Toran: Longsword.
Vorax: Battleaxe, Dwarven Waraxe or Greataxe.
Corath: Shortsword.
Pyrtechron: Greatsword. I think the classes themselves could use some customization and tweaking, but these are the current requirements as is, and they are missing from LORE. Thanks. (Edited for Pietechon)
