You can loot the stuff of dead traders from the ground. As a matter of fact, you should do so, if you don't do it, kobolds will steal even forbidden wares from outside and send ambush squads against you. And you could just massacre traders who waltz into your fort but refuse to trade, and take their stuff too. Unless of course they are fellow dwarves, you'd better not hurt those.
Yes, I discovered this. It's a consolation prize. Instead of getting just what I want from the caravan, I get random stuff for free.
It's a bit of an exploit, but I routinely build a 3 tile wide walled path from the trade depot to the map edge, and then seal off the last 5 tiles where you can't build walls with raising bridges, so nothing can get into that path from the rest of the surface. Caravans will only appear in that path. Diplomats and Liaisons will still appear randomly on any surface edge tile, so I need to have an alternate way into the fortress set up for them.
I did this on rephikul's suggestion. But it didn't quite work.
One trader spawned in the 3 tile zone. The others spawned way outside of it forcing me to drop the bridges, set an alert, and post squads in hopes, once again, that the traders could get in before getting run down. It does make the fort easier to defend though. So I'm grateful.
rephikul's other suggestion, checking the D key, gave unexpected results. The wiki says D is currently inaccurate and misleading but regardless, I just get a green blob island around the depot in a sea of red. "No access", it says. Incidentally, the green blob does have a 3-tile wide arm that extends a short distance from the depot. But these 3 green tiles are in the middle of a
5-tile open path.
Thoughts?
...This should land you some goblinite to melt down and then use in your own fort
I have no fuel for this "melt" that you speak of.
