Officially called "Limited Items" in Japanese, on the English fan forums they are more commonly referred to as the Japanese pre-order items. Each item is an animal plus one of the 7 sins. Stats aren't available yet. The items are all named in English and written in katakana. Currently only part of the stats of these items were revealed. For caster attribute related modifiers, the descriptions all say "skills" instead of "spells", although it should be "spells". None of the modifiers mention triggering conditions, but in general should not be assumed to be constant effects due to balance issues.
