Picked up a thunder stone from the Trader (Valheim), made the Obliterator in the building with all the other crafting tables and proceeded to give it a few trophies, to see how it worked.
Pulled the handle, but nothing happened right away.
CRACKBOOM!
I was sent flying three floor tiles away, the floors were damaged around it, and the ceiling above it was destroyed.
Amazing.
I moved it outside, fed it more trophies, and proceeded to cackle when I pulled the lever.
