My last fortress was destroyed ,dwarfs were killed and then I abandoned it. goblins came in the fortress by climbing walls ! (yes I didn't expect them to climb walls).
I thought of an idea to prevent them from climbing ,but I am not sure whether they will come inside by climbing it or stay outside ? I think this screenshot from minecraft can roughly explain the design.
(red line is the enemy path)
I wanted an open roof fortress not a fully covered top of fortress by floor. so is this feasible ?
Best Answer
Consider putting traps along the top of the floor level (along the outer edge) causing anyone to try and dodge, and hopefully dodge the 'wrong' way causing them to fall off (increase this by building a wall one step 'inwards'.
Another step you can take is to add fortifications, this has two advantages:
Repeat as many times as necessary ;)
Some animals are legendary climbers (cats are by default, and Giant Cave Spiders can move at 'walking speed' when climbing); so if they can swim as well then you're current defence would possibly still fail to them.
Also this defence does nothing to stop flying coughDragoncough enemies from entering your fort from above. The only way to truly stop anyone 'climbing' into your fort is to seal the roof off. After all, who wants the 'orrible glowing sky fire shining on them while they work anyway?!
