I’ve just added the following to the OP:Frostwyrm Lair
- Once players have cleared all four wings and entered Frostwyrm Lair there is no teleporter or other method to return to the lower levels of Naxxramas.
This includes leaving the instance and returning, as you will be ported directly to Frostwyrm lair upon Entering Naxxramas once the portal has become activated.
