Divine Nature. The avatar has advantage on saving throws against spells and magical effects, and any creature that makes a spell attack against the avatar has disadvantage on the attack roll.

Dragon-God of Time (Mythic Trait; Recharges after a Short or Long Rest). If the avatar is reduced to 0 hit points, he doesn’t die or fall unconscious. Instead, his current hit point total resets to 500 hit points, he regains any expended uses of Legendary Resistance, and he recharges his breath weapons. Additionally, the avatar can now use the options in the "Mythic Actions" section for 1 hour. Award a party an additional 155,000 XP (310,000 XP total) for defeating the avatar after this trait activates.

Legendary Resistance (5/Day). If the avatar fails a saving throw, he can choose to succeed instead.

Time Master. The avatar is immune to spells and other abilities that affect time such as Time Stop unless he chooses to be affected. If time is altered, he is aware of any changes made.
Multiattack. The avatar makes one Bite attack, one Claw attack, and one Tail attack..

Bite. Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 23 (2d12 + 10) piercing damage, plus 22 (4d10) force damage. If the target is a creature, it is grappled (escape DC 20) and is restrained until this grapple ends. The avatar can have only one creature grappled this way at a time.

Claw. Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 21 (2d10 + 10) slashing damage.

Tail. Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 23 (2d12 + 10) bludgeoning damage. If the target is a creature, it must succeed on a DC 27 Strength saving throw or be knocked prone.

Banishment (1/Day). The avatar casts the banishment spell, requiring no spell components and using Personality as the spellcasting attribute (spell save DC 27).

Dragon Shouts Recharge (4-6). The avatar uses one of the following dragon shouts (list of dragon shouts, save DC 27 for a dragon shout that requires a creature to make a saving throw):

castigate anomaly, elemental breath, righteous flame, slow time, unrelenting force

Drun Uth Vennesetiid (Castigate Anomaly). The avatar exhales a warping breach in the fabric of the Mundus in a 300-foot cone. Each creature or object of the aspect’s choice that is either native to another plane of existence or that is affected by a spell or magical effect that displaced it in time (for example, time travel) must make a DC 27 Personality saving throw or be instantaneously returned to their native plane or time.

Revak Jun Shul (Righteous Flame). The avatar exhales white-hot fire in a 300-foot cone. Each creature in that area must make a DC 27 Agility saving throw, taking 71 (11d12) radiant damage on a failed save, or half as much damage on a successful one.
Bonus Actions
Change Shape. The avatar magically transforms into any Humanoid or Beast, while retaining his game statistics (other than his size). This transformation ends if the avatar is reduced to 0 hit points or if he uses a bonus action to end it.
Legendary Actions
The avatar 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. The avatar regains spent legendary actions at the start of its turn.

Attack. The avatar makes one Claw or Tail attack.

Furious Bite (Costs 2 Actions). The avatar makes one Bite attack. If the attack hits a creature, the target must succeed on a DC 27 Willpower saving throw or become frightened of the avatar until the end of its next turn.
Mythic Actions
If the avatar's mythic trait is active, it can use the options below as legendary actions for 1 hour after using Dragon-God of Time.

Doom of Lorkhan (Costs 3 Actions) The avatar uses his Dragon Shout, regardless of whether or not he has recharged the ability to do so.

Flames of Contingency (Costs 2 Actions) The avatar conjures sheafs of white flame that surround his form. Until his next turn, melee and ranged attacks deal half damage and the aspect can choose to redirect the damage to another creature within 120 feet of him. A creature cannot be affected by this action more than once per round.

Regional Effects

The region surrounding Alduin is altered by the great dragon’s magic, creating one or more of the following regional effects:

  • Time Warp The area within 10 miles of the Avatar of Akatosh fills with indistinct whispers and harmless phantasms of past, present, and future of the area. A creature can succeed on a DC 27 Intelligence (Arcana) check to decipher these visions.
  • Bastion of Good. The area within 5 miles of the Avatar of Akatosh causes daedra and evil creatures to feel unease, with the possibility that they avoid the area entirely.
  • Aetherial Radiance. The area within 2 miles of the Avatar of Akatosh causes all flames, the effects of dragon shouts, and breath weapons to turn ghostly white. Any target that would take fire damage in this area instead takes radiant damage.

If the Avatar of Akatosh is defeated, these effects fade over the course of 1d10 days.
