Skeletons
Skeletons are fleshless corpses imbued by necromantic energies with a mockery of life. Most often, spellcasters create skeletons to act as guards and servants, but it’s not unheard of for skeletons to arise from cursed grounds where the living are outnumbered by the unburied dead.
Following Orders. Skeletons follow their creators’ instructions to the best of their limited ability. They understand language and can follow detailed instructions, but their ability to think independently is limited. If ordered to cross a dangerous river, a skeleton may take a detour to use a bridge. In the absence of a bridge, however, it will risk a dangerous swim rather than build a raft or search for a safe place to cross.
Shreds of Memory. If left to its own devices, a skeleton without orders may mimic habitual activities from its previous life. A skeleton will abandon such pursuits to attack living creatures, unless it has been specifically ordered otherwise.
Undead Nature. A skeleton doesn’t require air, sustenance, or sleep.
