Dragonbite Spear (weapon) (Patreon)

While this is a non-magical weapon made from the tooth of a dragon, it hurts creatures just like a magical weapon.

Get it close to a dragon and the living dragon's magic affects the tooth.

I originally created this a couple of years ago, but shelved it until today, when I fixed up the description a little. Now it's a nice treasure that might be gifted to those dragon-hunting PCs out there (or maybe even someone that did a favor for a dragon, or even something for a warlock with The Dragon patron).
