Both regions get the same pre-order bonuses, such as the two character costumes and three magical aids for battle. Those aids are the Spirits' Flamepike, which spears a fiery five-hit combo attack, the Spirits' Blightstone, which stirs up a poisonous explosion, and Spirits' Fulgurwood, which can both track enemies and cast a thunder spell.
The most curious bonus is that of Japanese voice-overs. It's always great to have the option, but tying it to pre-orders is certainly unusual. If you're not gonna sacrifice your dosh for the pre-order, take note that the voice-over pack will be sold separately. %Gallery-177521%
