Uh, build a fence around your base where your workbench area of effect ends.

I started a fresh toon this week with the plan of killing all bosses without using any glitches. No moats, raised earthen walls, clipping, or using stagbreaker AOE to find silver. Just build a base and use fencing to secure it.

First base was at Meadows/Forest boundary inside a larger dwarf tower. Got some boars, bees, carrots, and turnips going there. Have had both dwarf and troll raids, no issue. Just repair fence once event ends and mobs dead.

Second 'base' is on Elder platform after I killed him. There is a swamp a couple hundred yards from there. Found a couple crypts so far and also some sertling spawners. No stones yet showing me Bonemass location though =/ Hopefully this second crypt I just found will have a stone.

It is actually much easier play than I would expect, considering my first partial playthrough to silver era where I only killed Eikthyr. Give it some time, you'll get it figured out.

One major difference I am finding on this play Is that I am skipping many items and also not upgrading to them to max. First play I got every shield, bow, mace, etc and max upgraded before moving onto next area. This time I went from wooden shield to banded, skipping bronze completely. Also only had lvl 1 bronze mace before getting an iron mace. There is much less grind this way.
