i got the "A" item but how i put in on the mix oO?

Do you have the rest of the recipe?

hi , do you know what is this???

Those items upgrade dogis and other accessory items like hats.etc but they have a chance to brake them. When upgraded it can give 2 random item effects for example 10 strength and 10 dodge. If the item breaks a wagu coin will be given to you

^ not all the time though. People have used them and broken a dogi and received no wagu.

anybody know what is this item?

It is an unbind coin. It allows you to unbind binded items.

any info on how to use it??

Take it to an unbind station (normally next to an auction house) and put it and an item you want to unbind into it

The Unbinding station next to the Ah
There is a picture of it Here

And Here is a thread explaining how to use it
