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.

Hey! What's with the little "LK's" thing?

I'm so glad you asked! To keep my homebrew creations separate from official material in my collections, I mark everything I mark with "LK's," which keeps it sorted separate from everything else and lets everyone I'm playing with know that this isn't RAW material, especially if I'm sharing for a campaign I'm playing in. This is something I'm slowly implementing to my already published homebrew on the site as well, giving everyone who uses my content the same heads-up. It also marks this as something I've made by attaching my online initials to the content.
