Source Monster Core 2 pg. 131Rune dragons have an innate insight on the power of runes. Most rune dragons keep a variety of runes etched on their scales, which their bodies can magically empower. They typically don't cast spells themselves, instead relying on their ability to create runes on the fly to produce desired effects. A rune dragon often refers to their hoard as their library, as it's full of important historical texts, plays, speeches, textbooks, and spellbooks written by people of different cultures in a variety of languages. While they can often speak a language with the aid of magic, they much prefer to learn languages in the context of their speakers so they can grasp the nuances hidden within the syntax and the magic within their symbols.

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.
Alternate Abilities
Many rune dragons find alternative ways to utilize their mastery of runes. Any one of the following abilities can be mastered by rune dragons. Remove Entangling Rune and replace it with one of the following.
Adult Rune Dragon:
Runic Jail [one-action] (
arcane) The rune dragon conjures a prison that promises pain to those within and those who try to escape. The dragon creates a runic jail in a 10-foot
burst up to 60 feet away. The area is
difficult terrain and creatures outside the jail become
concealed to creatures within it. If a creature uses a
move action to leave the runic jail, they gain a detonating rune. The runic jail lasts for 1 round, but a creature adjacent to the jail, but not within it, can use an
Interact action to remove the rune early.
Catalyzing Rune [one-action] (
arcane) The dragon creates a highly reactive rune in a 30-foot
burst up to 60 feet away. Whenever a creature takes damage from a detonating rune while within the area, all other creatures in the area take the damage of the detonating rune (
basic Reflex save DC 34). The Catalyzing Rune lasts for 1 minute but can be removed if creatures adjacent to the rune spend two
Interact actions.
Ancient Rune Dragon:
Runic Jail [one-action] (
arcane) As adult rune dragon, but the area is a 20-foot
burst.
Catalyzing Rune [one-action] (
arcane) As adult rune dragon, but the area is a 40-foot
burst and the DC is 41.
Rune Archdragon:
Runic Jail [one-action] (
arcane) As adult rune dragon, but the area is a 30-foot
burst.
Catalyzing Rune [one-action] (
arcane) As adult rune dragon, but the area is a 60-foot
burst and the DC is 46.
Runedragon Spellcasters
If a spell the rune dragon casts would deal energy damage, it instead deals the damage type associated with its Shifting Runes. Additionally, rune dragon spellcasters know the
rune trap ritual and can fulfill the role of the secondary caster themselves. Rune dragon spellcasters tend to focus on specific types of magic such as ice magic or summoning. The following represents a rune dragon with a broader array of spells.

Trohalix
The rune dragon Trohalix keeps a lair hidden in the deserts of Thuvia. She ensures that rumors of her vastly supplied library are well known, but the exact location is not. Those who seek her knowledge can access the library for a time, depending on their donation, and anyone foolish enough to steal from her rarely lives to tell the tale.
