I've been searching to an answer for this, but haven't been able to find one. If I have an Argonian blacksmith (for example) in the EB, and am currently playing a character in the AD, would I be able to use the Argonian to craft and bank the items so that my AD character can use them?

I would test it this weekend, but I might not have much time at all online.

Thanks.

I dont see why not. The bank is shared between all characters.

that should not be a problem at all

Course, unless your Argonian has a lot of style books, your Elf or Kitty is going to be wearing Lizard armor

Which will stand out on Auridon, but it's cool to be different!
