Flaming sphere
This is a quick-and-dirty remix of mz4250's Flaming sphere.
The original model is very nice, but since in my group's D&D games the flaming sphere gets parked on top of enemies instead of next to them(I think this may have changed with the 2024 rules), a model that requires a space of its own didn't really work for us.
So, I flattened the bottom of the sphere so it doesn't roll all over the place. Then I flattened the top as well, to make a space where the target enemy's model can be placed, as demonstrated by Pikachu in the photo.
