What about fertilizers for crops? I know it's been suggested before, but I think it's a perfect item to add to dungeons. (I think the bat dungeon rewards are really weak)
Since you already implemented some sort of system to buffer time grown into tiles, what about introducing stuff only found in dungeons or foraged, that can increase the speed of crops? like some beaver dung fertilizer or something, that you can boost your crops with? That way, if you want the best ql crops, you have to go out in the world. (i.e. farming bots will not own the best crops)
I think farming is very detached, monotonous, and dependant on nothing else. Noone from my village knows the poor girl who's actually making all the food for them. It would be nice if they could go out and get stuff for her so there would at least be some social connection the other way back, if that makes sense.
Right now, dungeons only hold egoistic rewards. Fighters go to dungeons to get hearts to boost their HP, and needles to improve their equipment. But they are not really bringing anything back to the village. In the early world, the village is hugely dependant on having fighters to gather high quality bones and hides, but after a while, late into the world, the fighters only need to think about themselves, and the village is never really expecting them to collect or do anything.
