Uvar, The Stormfather

Amphibious. Uvar can breathe air and water. 

Legendary Resistance (6/Day). If Uvar fails a saving throw, it can choose to succeed instead.

Divine Storm Aura (Aura, 120 ft.) A crackling tempest surrounds Uvar. Creatures of his choice in this area have disadvantage on Dexterity saving throws and cannot benefit from invisibility or magical silence. Enemies that start their turn in the aura take 14 (4d6) lightning damage and 14 (4d6) thunder damage.

Legend of Order. Uvar’s presence enforces the natural law. Spells that impose charm, fear, confusion, or madness automatically fail within 120 feet of him.

Skyborn Sovereignty. Uvar is unaffected by gravity, environmental effects, or difficult terrain. He always acts first in initiative unless surprised.

Magic Resistance. Uvar has advantage on saving throws against spells and magical effects.

Magic Weapons. His attacks are considered magical.

Multiattack. Uvar makes three attacks with Skycleaver or casts a spell and makes two attacks.

Skycleaver (Mythic War-Axe)

Melee Weapon Attack: +19 to hit, reach 20 ft., one target
Hit: 45 (6d12 + 10) slashing damage plus 22 (5d8) lightning damage.
On a crit: The target must succeed on a DC 27 Constitution saving throw or be disintegrated in a pillar of thunder. On a success, it takes double damage instead.

Storm Breaker (Recharge 5–6)

Uvar slams Skycleaver into the ground, creating a 90-ft. radius shockwave. Each creature of his choice must make a DC 27 Dexterity saving throw, taking 88 (16d10) thunder damage and be knocked prone on a fail, or half damage on a success. Creatures that fail by 5 or more are also stunned until the end of their next turn.

Call the Tempest (1/Day)

Uvar summons a divine storm across a 1-mile radius centered on himself. This functions as a Mythic Storm (see Mythic Actions) and lasts 1 hour, moving with him. Within it:

• All ranged weapon attacks have disadvantage.

• Spellcasters must roll a DC 20 Constitution check or lose concentration each round.

• Each round, a random bolt of divine lightning strikes a hostile creature (12d10 lightning).

Spellcasting

Uvar is a 20th-level spellcaster (Wisdom +9, +18 to hit, DC 27). He prepares the following domain spells:

• At will: thunderwave, command, lightning lure

• 3/day each: destructive wave, wall of force, chain lightning, banishment

• 1/day each: storm of vengeance, holy aura, meteor swarm (as thunder/lightning variant)

Tempest Command (Recharge 4–6)

Uvar speaks a single word of storm-law, commanding the elemental forces around him.

Effect: Uvar chooses up to 3 creatures he can see within 120 feet. Each must succeed on a DC 27 Constitution saving throw or be either pushed 60 feet, knocked prone, or blinded by lightning (disadvantage on attack rolls and ability checks until the end of their next turn). He chooses the effect per creature.

“His voice is not heard—it is obeyed.”

Skycleaver Reversal

When a creature misses Uvar with a melee attack, he may channel divine wind to punish their arrogance.

Trigger: A creature misses Uvar with a melee weapon attack within 20 feet.
Effect: Uvar immediately makes a single Skycleaver attack against that creature. If it hits, the target must also succeed on a DC 27 Strength saving throw or be launched 30 feet into the air and knocked prone.

“Miss once. Learn what the sky does to fools.”

LEGENDARY ACTIONS

Uvar can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn.

• Storm Step. Uvar teleports up to 120 feet to a space in the air, leaving behind a blast of thunder (10d6 damage in 10-ft. radius).

• Wrath of the Sky. Uvar calls down a bolt of lightning on a visible enemy. DC 27 Dex save or take 42 (12d6) lightning damage.

• Thunder Reprisal (Costs 2). When hit by a melee attack, Uvar releases a burst of thunder. All enemies within 15 feet take 28 (8d6) thunder damage and must succeed on a Strength save (DC 27) or be knocked prone.

MYTHIC TRAIT: Tempest Incarnate (1/Rest)

When Uvar is reduced to 0 HP for the first time, the storm surrounding him erupts. He regains 500 HP and enters his Mythic Form for the next 10 rounds.

While in Mythic Form:

• Skycleaver deals an extra 6d10 radiant damage.

• Uvar can take 4 legendary actions per round.

• Creatures within his aura automatically take 30 lightning + 30 thunder at the start of their turn.

• He can cast storm of vengeance once without expending a spell slot at will.

Mythic Actions (Only in Mythic Form)

• Lightning Crown (Costs 1). Uvar marks a creature with a crown of lightning. That creature becomes a lightning rod — all lightning attacks within 60 ft. are redirected to them until the end of their next turn.

• Storm Chain (Costs 2). Uvar throws a chain of lightning at up to 3 targets within 120 feet. Each target must make a DC 27 Constitution save or take 72 (16d8) lightning damage and be paralyzed until the end of their next turn.

• Judgment of the Sky (Costs 3). Uvar calls down a divine thunderbolt on a creature. The target must succeed on a DC 27 Dexterity saving throw or take 200 lightning and thunder damage, halved on success. This ignores resistances and immunities unless the target is a god.
