2 burglar rings?

[I Kinda Fail]

Does the effect stack? The wiki says it doesn't, but several people on the Steam and Stardew forums, including my friend, swears it does stack.

The light rings stack, the magnet rings stack, the iridium band attack bonus stacks, so it would make sense if the burglar's ring stacked... but the wiki says it doesn't. Does anyone know for sure? Any surefire way to test? I was thinking about "guaranteed drops", but sometimes slimes and bats don't even drop slime or bat wings, so I'm not sure if there's a way to test whether you'd get more drops.

All the reports saying it does work tested on dust sprites, and they said they normally got 1 coal without the ring, 2 with the ring, and 3 with 2 rings. But it's also possible for a sprite to drop 2 coal at once.

I just don't want to drop 20k on a ring that has no bonus, but would love getting more coal, iridium and gem drops in the mines.

Just tested it. They're wrong. Doesn't work with dual rings, heck now that I think about it, I had already tried this like a year and a half ago because I wanted more bugmeat since when the dungeon would refresh on floor switches before the multiplayer update you could easily make about 3-4k a day of bugmeat while scrounging for prismatic shards and ancient seeds off them, or gather amazing amounts of coal.

Hmm. Strange that only some rings stack. I wonder if vampire rings stack? Probably not, since it's "special"...

Oh well. Good to know. Was just hoping for more slime egg drops.
