The Declarations of Honor can be viewed on 3 plaques placed in the Codex Arena. These are a set of tenets, used as basis for the combat in the Codex Arena.
"Honor the Codex"
For truly honorable combat, all combatants must only use skills included in the current Codex. Each Codex holds a number of randomly selected skills for each profession. A new Codex is put into effect each day.
"Honor your Team"
For truly honorable combat, all teams must have four combatants, each of a different primary profession. No heroes or henchmen will be permitted in the arena.
"Honor your Profession"
For truly honorable combat, each combatant may only use elite skills from their primary profession.
