The final entry of Ossiarch Bonereapers for a while are the Kavalos Deathriders. They are the cavalry unit for the army and can be armed with either sword or spear. I went with sword because they offer rend which is a -1 to armor save. The mounts are bone constructs made from an assortment of animal remains. They also have the spirit skulls that make painting a bit of a challenge. This unit wasn't as bad with the skulls, but i still had to paint it in sub assemblies. In game terms I don't think the cavalry are the most useful, but I had to include at least one unit.
Next I'm going to switch gears and work on some more Minotaurs space marines
