Fafnheir
CREATURE 24Fafnheir is the fabled Father of Linnorms. He's larger than all other linnorms on Golarion, with a length of 60 feet and a weight upwards of 10 tons. Fafnheir is a clever and powerful creature, worthy of the fear of all people in the Lands of the Linnorm Kings.
A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.
This monster regains the listed number of Hit Points each round at the beginning of its turn. Its Dying condition never increases beyond Dying 3 as long as its regeneration is active. However, if it takes damage of a type listed in the regeneration entry, its regeneration deactivates until the end of its next turn. Deactivate the regeneration before applying any damage of a listed type, since that damage might kill the monster by bringing it to Dying 4.
[reaction] Tail only.
When a creature slays Fafnheir, it becomes home to his soul, which slowly emerges from his killer's body. The creature must attempt a DC 52 Will save or become Doomed 2 (Doomed 1 on a success, unaffected on a critical success). Unless the creature critically succeeded at the saving throw, each day the doomed value increases by 1. If the creature dies while suffering the curse of the woeful wyrd, its corpse explodes in a 60-foot burst with the effect of Blasting Breath. Fafnheir is immediately returned to life in the nearest available space to the corpse with full Hit Points and no conditions. Even an indirect slaying usually still allows Fafnheir to curse the soul of his slayer through the metaphysical link between them.
Fafnheir takes up a space of 6 squares by 6 squares (30 feet by 30 feet) and is 60 feet long.
Fafnheir gains 2 reactions at the start of each of his turns.

Fafnheir exhales a cataclysmic firestorm laced with lightning and hurricane-strength winds, dealing 20d6 fire damage in a 90-foot cone (DC 48 basic Reflex save). Additionally, Fafnheir deals 10d6 additional electricity damage to one creature within the area of Blasting Breath of Fafnheir's choice, determined by the same basic Reflex save. Creatures in the area must also attempt a DC 48 Fortitude save to resist the powerful winds and deafening thunderclaps of the breath. Creatures that fail experience the effects of Gust of Wind, affecting Large or smaller creatures as normal. Finally, creatures that fail their Fortitude save become Deafened for 1 minute (permanently deafened on a critical failure).
Fafnheir makes two claw Strikes and one Strike with his jaws, horns, or tail, in any order.
The monster can instead use Improved Grab as an action and choose one creature it's grabbing or restraining with an appendage that has Improved Grab to automatically extend that condition to the end of the monster's next turn.
