I'm about a month into my 43.05 fort. Our prospectors did well. We have hematite and marble in nice big veins up near the lip of the volcano. Our absolute first project was to build a magma bridge trap at the entrance. Two 10x3 retracting bridges with a 1 tile opening between them in the middle. There sits a pressure plate hooked up to both bridges. Directly below is a 21x3 magma pool 1 deep. It has 4 iron hatches at the bottom so I can drain off the loot. All the junk (bodies, loincloths, etc...) burns up leaving just the iron goodies. They get pushed down the drains into the channel that leads to an edge fortification to get rid of the magma. It takes about a month for the last of the magma to cool enough so I can send in the scroungers to pick up the loot. This has been the absolute best trap I have built. Watching 20 goblins run into the entrance just to have the ground fall out from underneath of them moments before they get to the fort is awesome! Now and then a sprinting troll jumps the last few feet to give my waiting melee squad a workout. Not having to do post siege cleanup is the best part. I have been able to focus on digging deep and crafting lots of cotton candy gear. It really makes for a lot more fun and a lot less !FUN!.
