I’ve been trying on and off for the past few months to get a cursed staff but it seems like they don’t drop them. I’ve actually fought so many of them that I’ve gotten at least 3 skeletal bat pet drops, which are supposed to be even rarer. I had a similar issue with ice staves where the wiki states that snow bats drop them but it seemed like they didn’t and I had to get them from snowmen, even though the wiki stated that they don’t drop ice staves.
