All fire vampires within 15 feet are not harmed and instead regain 14 (4d6) hit points. The explosion ignites flammable objects in that area that aren't being worn or carried.

Despite its name, the fire vampire is not related to the common undead vampire. Instead, fire vampires are spherical creatures that consist of living flame. They are said to originate from a faraway star. Fire vampires are sentient. If summoned, they appear as flaming meteors in the sky. A swarm of fire vampires is as beautiful as it is deadly and destructive.
