Items are banned from the Dungeonsport Coliseum for a variety of reasons, including the granting of wishes, unecessary slowing of the pace of combat, or because of a general lack of utility in the arena.
Sane Magical Item Prices was used as a starting point for pricing, but ongoing adjustments are being made to the pricing, and additional items continue to be added to the lists.
