How do I get to the battle dome/arena? I'm still not used to the new subeta changes. :(

It's in the Sacred Lands. :)

Or, subeta -> games -> Battle Coliseum

- I didn't know it had a place on the map. Pretty sad. Thanks. (even if I didn't ask.)

I didn't know it was under games, so we both learned something. xD

You may be thinking of another virtual petsite. There is no Battle Dome in Subeta.
