To access Ursa Caverns, click the Ursa Caverns button at the bottom of your screen or hit Alt + N to open a window allowing immediate access to Ursa Caverns (and the Deathmatch Arenas). You'll be teleported to the lobby of the appropriate tier (see below), between Gen Point Vendor Cleo and Warehouse Keeper Varona. Exiting Ursa Caverns (by clicking the Exit room button) takes you to your return location. You can use Ursa Caverns as a cost-free route to teleport from the field back to your return area. This renders return scrolls superfluous unless you need to return more than 12 times in a day.
