Where can I find DMS on map? Or I just use an item to teleport there? or like I have to be a curtain C.L?
You won't find it on the map because it's inside Deadman's Pass.
So next time you are in Bill's Ranch and want to scope the place out. Click on the gate to Deadman's Pass and pick easy. There will be enemies inside, so either take them out or run by them.
Once you are inside, go west, until the only direction is north. ((If you are by the stairs, you haven't gone far enough.)) Next, go up a screen and you'll find a gate. That gate will take you into Deadman's Shadow. ((If you are having trouble with these directions, then add me and I'll show you.))
You or the leader of the crew, will have to be level 10 or higher to go inside. Otherwise it will not let you in.
