Ancient Magma Dragon
Magma dragons represent a brash and volatile aspect of dragonkind. Territorial and unpredictable, magma dragons are known for protecting their hunting grounds with a fierce and proud demeanor that brooks no challengers. Passionate in the extreme, magma dragons in their draconic forms can often seem utterly bestial, impulsively jumping at threats and challenges with a wild abandon, but this belies an intellect that many underestimate.

WyrmwraithDragons come in myriad forms, with many having magical abilities or connections to magic. Some dragons draw greater power from magic than others, allowing them to manifest abilities or alter their physiques with prolonged exposure to magic. These dragons become more powerful as they age and strengthen their connections with their magical origins. Scholars debate the classification of these dragons, with some preferring the name magical dragons and others using traditional dragons due to their connection to specific magical traditions. Regardless of their names, these dragons share a number of characteristics: their ability to tap into magical energies, intensified might and cunning as they grow older, and an inclination to hoard vast amounts of treasure and wealth.
Draconic Spellcasters
Each dragon features a sidebar on spellcasting dragons of that type. To make a dragon spellcaster, remove the dragon's Draconic Frenzy and Draconic Momentum abilities, and give them the spells outlined in their sidebar. You can swap out any number of these with other spells, provided you keep the same number of spells for each rank. You might also want to increase the dragon's Intelligence, Wisdom, or Charisma modifier by 1 or 2 to reflect their mastery of magic.
