Question on the Mog Cap.

[Fleyon]

They're available to every character you make on the account that has those items. The items are account bound, not character. When you make a new character, they'll be in your mog mail.

Just to clarify to avoid confusion, it's all characters on one service account - not the entire Square Enix account.

I'm of the mind that these quirky pre-order items are mostly just for show, so I'm not too fussed about them not having a great stat benefit. I think it's quite cool to wear your pre-order items 5 years down the line to show your loyalty to the game
