Just a heads up that there are ways to place doors in the game.

Step Sowers are probably the best way for base building, since the walls are easely destroyed, if you misplaced them or want a different layout. They're also a great way to avoid death, since they can block enemy pathfinding.

There are other ways to place walls as well. No easy way to place doors, though. You could imbue a door with life, use Proselytize to make it your follower and then just tell your new door-buddy to stay put where you want a door to be.

So if you want more than just walls, with this mod, you can create entire home bases:

Thanks much, this is what I was looking for!

Don't thank me, thank the mod creator and the awesome community behind Qud. I'm pleasantly surprised, how many mods got updated for 1.0.

There is also an advanced version of the Step sowers that give you more choice with walls.
