So I made it throught the mountains, even though Moder can literally destroy Silver Veins buried beneath the ground, cuz about the only thing Moder cannot damage is the summoning base. Even destroyed my pillar of ground I erected to stand behind. Nothing does much damage so it took forever to take her down.
Now, I get into the Plains and hit and run a bunch of big guys till I find barley and flax, and wouldn't you know it... it has to be grown in the Plains, not home in the Meadows. XD
So after some trial and error, I managed to come up with this nice little shape to build up around this stone column to give me a Plains base. Peace build seed (kill no bosses), so this should work for what I need.
Gonna level the 3 platforms up the column, connect them with staircases, as shown, and tie cord wood into the column to continue foundational support. The bed/portal area sits under the column lean, so it is good at first floor level.
Time to get this set up and bring in the Plains Machines so I don't have to do so much map transfers.
