Today during Mage training I stopped at the portal trainer and was offered to learn to teleport to Exodar.
So I took it.
I had never been to Exodar and thought that might be an easy way to get there.
I tried it twice and although it used my teleport reagent NOTHING happened. Not even a message that I couldn't do that.
Do you have to have an expansion to go to Exodar? I googled it and it seems people have gone there.
