Wondrous Item, artifact (requires attunement by a someone with Gold or Red Dragon linage)
A large ruby set in gold. This amulet is said to contain the flames of Asgorath, creator of dragon kind.
The wearer of the amulet is immune to fire damage. If a fire spell would target the wearer, the entire spell can be absorbed, completely nullifying it. The spell can then be returned as a Hellish Rebuke of the same spell level when the wearer can next take a reaction.
The wearer's flames burn with such an intensity that none are immune to. Your fire spells and abilities treat Immunity as Resistance, and Resistance as neutral.
Notes: Immunity: Fire, Absorbs any fire spell or ability. For spells that would hit multiple targets, the entire spell is absorbed and all damage is nullified., someone with Gold or Red Dragon linage, Buff, Jewelry
