Oh god my fort is of so much awesome right now it's hard to explain. A full map picture couldn't show everything, because it's on multiple floors.
To start out with, I had a normal hill map. Instead of carving the fortress in the hill, I carved the fortress OUT of the hill. by that I mean I took away all of the hill that wasn't part of the fort, leaving a huge castle with a giant water tank (because it's a BCB re-challenge, and I need a place for to "distill"). On the ground floor, I have a siege that I've nearly destroyed ONLY USING RETRACTING BRIDGES. Yeah. I have a couple draw bridges that just repeteadly appear and disappear, and the goblins fall down and climb back up, occasionally getting injuries.
For my archers to get a good shot, I took THE ENTIRE SECOND LEVEL and made it into fortifications. Now I see only a rain of bolts.
A hill titan out of sand arrived. Three shots, titan dies, now my squad leader is an elite crossbowdwarf.
Siege still going on when a Giant arrives (early world, tons of mega and semi mega beasts). Giant somehow makes it past my moat and a legendary wrestler punches him to death.
Siege still going on, nearly a year later. They only have archers left, which is the reason I haven't attacked them directly. I don't want to lose anybody (and so far I haven't)
I had had two big rooms full of water connected directly to my moat as my stills, but they weren't awesome enough. I drained them through my fortress carefully and then into the caverns, so I could build walls.
That took 20 lives. Still no tantrums
Siege still going on. They have literally one troll. One troll.
Remember that thread where I had a river that emptied faster than it filled? Yeah? Well that's where he was hiding, right where I had hoped he WOULDN'T. I dug out that area and he ran out, killed the miner who freed him, took the pick axe, and the proceeded to kill almost my entire squad of axedwarves. He became a fucking TROLL MINER because of how he used the pick.
My elite crossbow dwarf who killed the sand hill titan killed the troll miner deadededed.
