New enemy figurine drop rates?

Kind of a subjective feeling, but I feel like the new enemies have a much lower drop rate for their figurines than mobs usually do. I have a farm setup where I'm able to gather 20-50 void clubs and another 20-50 of the new amulets every 15 minutes or so, and still haven't found a single figurine from a void enemy. 2/3 on the robots so far.

How is everyone else doing on their figurine collection?
