Alkalyne's Gaze: One creature Alkalyne can see within 120 feet of him must succeed on a DC 22 Wisdom save or be feared for 1d10 rounds. Feared targets must use dash each turn before it can reroll for the save. If the creature succeeds its save it is immune to Alkalyne's gaze for 24 hours.

Breath Weapons (Recharge 1d6 rounds). Alkalyne uses one of the following breath weapons.

Radiant Breath. Alkalyne exhales a 10 foot wide beam of radiant energy extends 90 feet in a straight line. Each creature in that area must make a DC 24 Dexterity saving throw, taking (16d10) radiant damage on a failed save, or half as much damage on a successful one.

Fire Breath. Alkalyne exhales fire in a 90-foot cone. Each creature in that area must make a DC 24 Dexterity saving throw, taking (16d10) fire damage on a failed save, or half as much damage on a successful one.

Weakening Breath. Alkalyne exhales gas in a 90-foot cone. Each creature in that area must succeed on a DC 24 Strength saving throw or have disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Smite. Three times a day Alkalyne can channel his divine radiance into 3 beams. Each beam of divine radiance deals 8d10 radiant damage. Non evil aligned creatures must succeed DC 24 Dexterity save to take half damage. Evil aligned creatures take double damage. Beams must be cast within 60 feet of Alkalyne.

Change Shape. Alkalyne magically polymorphs into a gnome or beast that has a challenge rating no higher than his own, or back into his true form. He reverts to his true form if he dies. Any equipment he is wearing or carrying is absorbed or borne by the new form (Alkalyne's choice).

In a new form, Alkalyne retains his alignment, hit points, Hit Dice, ability to speak, proficiencies, Legendary Resistance, lair actions, and Intelligence, Wisdom, and Charisma scores, as well as this action. His statistics and capabilities are otherwise replaced by those of the new form, except any class features or legendary actions of that form.

Alkalyne can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Alkalyne regains spent legendary actions at the start of its turn.

Detect. Alkalyne makes a Wisdom Perception check with a 120 foot radius.

Tail Attack. Alkalyne makes a tail attack.

Hurricane Wings (Costs 2 Actions). Alkalyne can create a Hurricane force gust of wind with his wings. The affected area is 30 feet wide by 60 feet long. Anything caught in the area must make a DC 24 Dexterity save to get out of the area or DC 24 Strength save if holding onto a solid object. Failing saves take 2d6 bludgeoning damage for every 5 feet blown back to the end of the affected area. If the item or creature is blown into a solid object it takes an additional 6d6 crushing damage from the force of the impact. Alkalyne can then fly up to half his flying speed.
