Dwarf shenanigans

I gave my players a sonic screwdriver-like key that had to be charged and could turn any door into a temporary entrance to a small pocket dimension, but I didn't tell them what it did. While the half elf was inspecting it, the dwarf decided to take it and smash it with his club. I had to give him inspiration for playing his character well (it was very in character for him), but damn, I was excited to see how they used it.
