==Muling with a Friend==
Go as fast as possible here, especially if they are just holding the game for you.  If you are using a common muling game with various friends or guild mates, and they are off playing then you don't have to hurry so much, but if they are waiting on you, don't keep them waiting. If you take 20 minutes screwing around with 50 mules, your friend will probably find a sudden need to be AFK next time you ask them for muling help.


'''1.'''  Godly (very important or very rare, includes runes) items MUST be held by the friend via trade screen.  It's not safe to leave them on the ground since the game might crash at any time.  As soon as you get the great item, leave the game so your character will be saved.

'''2.''' Less important items (mid-level charms, gems, starter equipment etc) can just be dropped on the ground and be picked up later by your mule. But make sure that when you pick the items up, don't spend time looking at the stats too long if you did a mule to character transfer. If your connection gets interrupted, whatever you just picked up is gone. Make sure to save and quit after you pick up the items.

'''3.''' This tip might not apply to most but make sure your friend is doing something while you transfer. Maybe finishing a quest or leveling up are good things to do. For some reason, some of my friends get disconnected if they stay idle for too long. Transferring with more than one friend in the game is much safer. You can have them duel each other for fun while you mule.
