Alchemical Hydra
Two rolls on the drop table per kill, on top of the bones. Only the first can be a unique; the second is always standard. The brimstone ring pieces come in a fixed order — eye, then fang, then heart — so only the one you're missing is ever rolled. A further 1/101 of kills roll the shared rare drop table, which has its own page here and isn't included in the rows below.
