Blizzard's October 1 development notes raised the beta level cap to 30. The update also made the Excavation Site: Wetlands available for levels 26–31, alongside Razorfen Downs (25+) and Uldaman (30+).
How to use this information
These level ranges describe the beta notes at the time of publication; they should not be interpreted as a guarantee of final tuning or recommended group composition. Check current notes before planning a route around a particular dungeon.
For AzerothMarket's dungeon records, each entry should keep its own level range, testing status and source date so beta changes do not overwrite historical context.
