Layering is the World of Warcraft: Classic alternative to the sharding technology. It allows a realm to create several instances of itself to balance its own population, instead of balancing players around shards from multiple realms.

Unlike sharding, players won't be able to leave the layer to find a better one when moving to different zones. Currently, the only way to change to a different layer is to join a group, which pulls all the players from the group into the same layer.[1]

Every layer is a copy of the entire world, so you can kite Anachronos all the way to Orgrimmar, and you can ride the boat from Ratchet to Booty Bay with the same people alongside you the whole way.[2]


  • This technology will only be around for a week up to a month after Classic's release but will not come back for any of the phases after Phase 1; this is to avoid disrupting the flow of the world bosses and other content.[1][2] The layers will be reduced to one per realm before Phase 2.[3]
