Thanks, not sure there's room enough for a decent earth wall but will double check. Also digging down to sea level around the pillars so should see a few extra meters. I'm not adverse to fighting it out with the trolls once I get properly buffed and geared but I've yet to build the kite track also working on log jam - hauling most lumber in remotely, leaving most of the trees around lay where they fall. Might need to plant some more...

The Abom's can't hit if you're on top of a crypt, pretty sure they can't go above 4 meters, maybe 5. Also thinking about reinforcing the floor with beams and one meter intervals in case 2* archer or horde of archers come visiting. Had that happen with the elevated cartway covered bridge in the swamp, then I could just keep moving so they never got to concentrate on one spot. Not sure how they'll behave with elevated base.
