Dont have defenses.

I took the hint early on, and have a ridge of "ground" deformed up into a wall all around my entire base. It's the base layer of the terrain, there's nothing under it in the game, and it's indestructible. It makes it a little annoying to get in and out (I have to "run" up a sheer wall), but enemies can't get inside at all.

This is what I've been using ever since three trolls nearly destroyed my first big house. I found out the hard way that trolls will actually spawn in water, and simply walk through it. I built on a peninsula with water on three sides, and just assumed that meant attacks would only come from the land side. Nope.

The only raid that is slight annoying is the one with ice drake/wyverns, since they can fly. But there usually aren't a lot of them


A bit of advice: make what I call a "battle box". Stock it with extra arrows, extra weapons, Food, drink, meds. Just get disciplined about not borrowing out of it. Knowing you have backup supplies sitting there whenever you need them makes those things easier.
