So, I am glad someone caught that the Minotuar skeleton was nerfed, but there are some small things here and there I want to point out.
Skeletons are deadlier in this. +1 to hit and to damage compared to 2014.
Skeleton Warhorses deal less damage (7 instead of 11) but gain the ability to knock prone on a charge. Additionally, the old entry didn't say anything about them, just gave us the statblock. While it isn't much, the inclusion of the lore bit that the skeletal warhorse is often ridden by its dead master tells us that the statblock should actually be used with the skeleton or another undead... and it is the first block next to the skeleton. Nice little design there.
Despite all the statblocks being evil, I appreciate that the lore doesn't say that they are inherently evil, and actually says that without orders, they sort of just bumble around. Like that.
For all those planning on giving skeletons a fear aura, reconstructing bones, clouds of choking dust, weapon masteries, six kobolds in a trench coat and a cherry topper... some of those are great ideas for making unique or scarier skeletons. But let us keep in mind that these guys are the least interesting and least powerful of the undead. Zombies have their fortitude, and after that you are mostly dealing with incorporeal undead and wights.
Nothing wrong with the armies of the BoneMonger having scarier abilities, but it is nice that jilted teen Janice who learned to animate some bones has some trash mobs for a low level party to smash through.
