This dragon bone is carved with necromatic glyphs, allowing the user to summon an undead warrior.

As an action, you can speak the command word and drop the bone to the earth. Doing so summons a skeleton. It acts on its own initiative, and obeys all of your verbal commands. The skeleton does not take any actions of its own, but it will defend itself if attacked. The skeleton lasts for 1 week before collapsing into a pile of bones.

Depending on the variety and age of the dragon it was made from, the skeleton gains some extra traits:

• Wyrmling Dragon Bone: Nothing. (Rare)
• Young Dragon Bone: Resistance to the dragon's breath weapon damage type. (Rare)
• Adult Dragon Bone: Immunity to the dragon's breath weapon damage type. (Very Rare)
• Ancient Dragon Bone: A pair of wings sprout from the skeleton's back, granting a flying speed of 30 feet, in addition to immunity to the dragon's breath weapon damage type. (Legendary)

You can reanimate a skeleton that has collapsed using the animate dead spell. However, the normal rules for maintaining control over undead apply at that point.
