If defenses in one tunnel don't work, lock it down, and leave a different one open, so that they have to run back through your killzone to try approaching a different one. At first, you might simply dig into a wall and put up a door, but consider making a large, extended underground tunnel, or preferably several tunnels, all of which can be locked down, and then walling over your initial entrance so that you can force enemies to approach your fort on your terms, and at a time and place of your choosing. Enclosed caves are also proof against flying monsters. Either carve or build unclimbable fortifications, or else dig another z-level down, and then dig two tiles under the rim of your platform to create an overhang that is impossible to climb.Įxcavating fortresses by digging them out naturally creates walls, and makes for easy defenses, since it is far easier to designate for digging than to build a wall. Climbing, however, makes this not enough for all circumstances. Easier still is just using the "natural walls" of a hill, and removing all the ramps on one side or the other of the hill while building walls between the gaps. Place fortifications at the tops to stop climbers.ĭigging ditches/ moats, then removing the ramps can also be useful as a faster method of creating impassable terrain for non-fliers, which have the added advantage of allowing marksdwarves to shoot over them.

However, since the advent of climbing, keep in mind that just having 1-z-level walls are not enough. The longer invaders take to reach you, the more time you have to get your militia in place. Putting a wall between your vulnerable and valuable civilians (and the others, too, why not?) and the things trying to kill them is the highest priority you have.īuilding walls can take time and micromanagement, but building a maze (and stuffing it with traps) is a good way to slow invaders down, especially if you get forewarning from scouts.


Walls are currently invincible against any known force but the mighty dwarven pick. Walls are, by far and away, the single most powerful tool you have to combat enemies.
