Slippers, obviously. That insta-warp you home when you click the heels. Those I’d buy.
Actually, back when you first made the ruby hammers, I bought one. It was my first ever gem hammer and I felt like a total badass. And then I died, TWICE, on the way home… Now I’m too scared to actually take the thing out of its cupboard. I still haven’t hit a single rock with it. So ends my tale of woe.
I’d buy a grapple, though. At least I’d get to use it on the way to my inevitable death…probably?
