Nostalrius Begins - Quality wow vanilla realm (1.12)

Multiboxing refers to playing multiple separate characters simultaneously. This can either be achieved by using multiple separate machines to run the game or by running multiple separate instances of the game. It is against the rules to /follow level characters, run dungeons or raids with multiple characters, PvP with multiple characters, etc. There are only a few situations where multiboxing is allowed in Nostalrius, e.g.:

Trading items between accounts.
Professions, as long as no farming is involved;
i.e. You can have two characters ingame simultaneously for crafting, enchanting, or trading purposes.
