Feat: Bone Speaker

To truly understand the mechanical advantages of an undead skeleton, you must understand how it functioned in life. You can Recall Knowledge on living creatures with an internal or external skeleton using Undead Lore. If you do, you can learn only information pertaining to the biology of a creature—not any learned abilities or abilities granted by items.

Additionally, you can perform a forensic examination on a corpse using Undead Lore instead of Medicine if the corpse came from a creature with a skeleton.
