A reanimated Skeleton of a Horse, this creature was often found as a mount for many types of undead humanoids. They retained a similar nature to its living counterpart, often acting docile and demure even when confronted with life. Many stories were written about how living humanoids became cursed after riding skeletal horses, but no evidence of such an occurrence was ever found.
A skeleton's brittle bone structure made it vulnerable to bludgeoning damage, but it nonetheless showed no hesitancy in slamming itself into foes when required.
