Right now, the only drop listed for the “angry ghost” enemy is a single ghostly ectoplasm with no known drop rate.
However, the wiki shows that it drops three ghostly ectoplasm: the first has a rate of 100%, the second has a rate of 10%, and the third has a rate of 1%. As this particular monster is very relevant to Standard right now, there’s been a lot of spading done on that.
I’m not quite sure how to add item drops for monsters (it appears to be in multiple places, and I’d probably miss a few), so I’d appreciate it if someone made this change on my behalf.
