Add telescience blocks on the mining Z-level

[BaneOfGiygas]

Basically, loot chests with loot lists corresponding to the dangers faced. It could range from clothing on low lists to low/med level syndicate items on higher lists. Some old places would probably need more critters, and some new, more dangerous places would probably need to be added, though.

Well, this is probably what the abandoned crates are supposed to be, but no one ever seems to go through the trouble of unlocking those things and you typically just end up getting a bunch of cats when you do, so the loot could stand to be more useful instead of being the gamut of medical supply beakers, hobo wine, and Discount Dan snack cakes.
