Breath Weapon [>>] (divine, electricity, evocation) The dragon shoots a ball of electricity that deals 7d12 electricity damage in a 25-foot burst within 50 feet (DC 33 basic Reflex save). They can't use Breath Weapon again for 1d4 rounds. See divine lightning below.

Coiling Frenzy [>>] The dragon makes one claw Strike and one tail Strike in either order, each against the same target. If either Strike hits, the dragon automatically Grabs the target.

Divine Lightning (divine) A good sky dragon who worships a deity channels divine power through its attacks, making them more effective against fiends and undead. Any electricity damage it deals becomes good damage against fiends or positive damage against undead.

Draconic Momentum The dragon recharges their Breath Weapon whenever they score a critical hit with a Strike.

Greater Constrict [>] 3d8+8 bludgeoning, DC 33 (page 305)
