Phoenix

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.

When a phoenix dies, they collapse into a pile of smoldering ashes before returning to life fully healed 1d4 rounds later, as if subject to a 7th-rank Resurrect ritual. Self-resurrection happens only if there are some remains to resurrect; for instance, a phoenix killed by a Disintegrate spell can't use this ability. A phoenix whose remains rest within an area devoted to an unholy deity by Consecrate can't self-resurrect until their remains are no longer in that area. A phoenix can self-resurrect only once per year.

20 feet. 4d6 fire, DC 37 reflex save. While this aura is active, any adjacent creature that hits the phoenix with a melee attack or otherwise touches them takes 2d6 fire damage. The phoenix can activate or deactivate the aura with a single action, which has the concentrate trait.

The phoenix blazes with superheated flame and Flies up to their Speed. They deal 6d6 fire damage to each creature within 20 feet of each square they move through (DC 37 reflex save).
