The characters in our AD&D campaign had to fight lots of these guys. They were quite a challenge. The ability of devils to summon more devils makes things difficult. Their magical at-will abilities to cause fear, fly, and create illusions, along with their strength-sapping attacks and poisoned tail spike give the characters fits.
I gave this Reaper mini a base of skulls, and then added a bit of blood so things didn’t look quite so…dry. He came with a pair of raggedy wings that I decided to leave off.
