When I had animals, I made lots of omelets, and had kept them on hand to use as food for adventuring.
Eventually I had spent so much time in the mines and dungeon, that I ran out of food. I had never cooked anything else, and saved no produce for cooking, which meant... no food for adventuring. Which meant no adventuring.
I discovered that I could turn my maple syrup into maple bars (mmm) and so when I had a handful of those, I went into the dungeon.
In addition to wanting to max out my skills, I still did not have a prism shard. That was really bugging me.
I only had a couple bars, but nothing else to do that day, so I went into the dungeon just to see how far I could get. First level, I killed one of those bat things, it dropped a shard (!!!). There's like a .01% chance of that!
I left the dungeon immediately and went home to sleep so my game would save. And overnight I hit max rank on mining and adventuring.
So suddenly, with one bat killed, I had accomplished all my goals. Except I didn't. When I read the shard's flavor text, I saw that I need a second one for the museum. *sob*
Back to the dungeon with me.
