I don't understand what you are asking. Do you want to know about items that will help you level faster....or did you spell dual wield wrong and want advice on what boosts dual weild?
Please be more specific. By not being clear with your question I have to guess what it is you are asking. So I'll give it a shot and hope I didn't waste my time researching all these links.
First, items that boost dual wield, you will find a list of items in the link below.
Items/aids that will help you level faster....one not listed in a link are fast EXP parties in Abyssea. This is a very long list of items, with p probably a few I might of missed. Skyfiredancer (talk) 12:00, July 26, 2015 (UTC)
