Muling is the transfer of items from one character to another, usually between two of the same player's characters, though not necessarily. Any item you attempt to mule gets deleted and your reported to the DMs. However, it's an exploit, and horrible RP. Try to rationalize it as you will, there is no Role Play reason for a character to just happen to give items to someone they've never met, nor can possibly be involved with. And they can't. So don't. Whatever benefit you think you can reap from muling will not be worth the punishment it incurs. We will normally delete the characters used in the mule if this occurs, or your entire character vault if there appears to be a pattern, or if you're a repeat offender.
