For loot you can depend on …

The caverns, mines, and ruins now each have 1 weapon chest (random weapon type) and 3 weapon racks (one for each weapon type).

The caverns did not change. The mines went from 2 chests and 3 racks to 1 chest and 3 racks. And the ruins went from 4 chests to 1 chest and 3 racks (plus the ruins boss racks, if unlocked).

Player feedback in the forum led to this change.

Sounds like a nice little extra, thank you.

Thanks for this change. I think it will really help to be able to at least have one chance of getting the weapon you need from the ruins. I guess it was easier for you to implement the racks than make the chests contain a specific type of weapon :-)
