Blue Eyes Alternative Ultimate Dragon

Legendary Resistance (4/Day). If the Blue Eyes Alternative Ultimate Dragon fails a saving throw, it can choose to succeed instead.

The Ultimate Blue-Eyed Legend (Recharges after a Short or Long Rest). If the Blue Eyes Alternative Ultimate Dragon would be reduced to 0 Hit Points, its current Hit Points is instead reset to 450 Hit Points, it recharges its Breath Weapon, and it regains any expended uses of Legendary Resistance. Additionally, the Blue Eyes Alternative Ultimate Dragon can now use the options in the “Mythic Actions” section for 1 hour. Award a party an additional 120,000 XP (240,000 XP total) for defeating the Blue Eyes Alternative Ultimate Dragon after its Ultimate Awakening activates.

Three Heads Are Better Than One. When making a Wisdom (Perception) check or a saving throw against the Confusion spell or any condition it is not already immune to, the Blue Eyes Alternative Ultimate Dragon rolls three times and uses the highest result.  This includes charmed, deafened, exhaustion, fatigued, grappled, incapacitated, invisible, petrified, poisoned, prone, restrained, stunned, and unconscious.  Additionally, the Blue Eyes Alternative Ultimate Dragon gets two extra Reactions that can be used only for Opportunity Attacks.

Fusion Creature. A Blue Eyes Alternative Ultimate Dragon can only be created by fusing three Blue Eyes Alternative White Dragons together with Polymerization or another suitable fusion spell/ability/item.  Similarly, using De-fusion or a similar reverse fusion spell/ability/item on one will revert it back into three Blue Eyes Alternative White Dragons and any damage the Blue Eyes Alternative Ultimate Dragon received prior will be split between the three dragons.

Flyby. Blue Eyes Alternative Ultimate Dragon doesn't provoke opportunity attacks when it flies out of an enemies reach.

Ultimate Divine Majesty with Eyes of Blue. Now charged with the divine draconic energy of three Blue Eyes Alternative White Dragons, the Blue Eyes Alternative Ultimate Dragon's majestic body of sharp, crystal-like scales is even more lethal than its regular counterpart.  As a result, all of its melee attacks deal an extra 9 (2d8) Slashing damage and 7 (1d12) Radiant damage on each successful hit.

Alternative Creature of Destruction. When the Blue Eyes Alternative Ultimate Dragon rolls for a saving throw and fails, it can roll again and use the second roll instead.  If it rolled with Advantage/Disadvantage for the first roll, it also rolls with Advantage/Disadvantage for the second roll.

Spellcaster's Bane. Blue Eyes Alternative Ultimate Dragon can sense the magical nature of spellcasters and has Advantage on all attack rolls against them.

Unusual Nature. The Blue Eyes Alternative Ultimate Dragon doesn't require food or drink

Multiattack. The Blue Eyes Alternative Ultimate Dragon can use its Frightful Presence. It then makes five attacks: three with its bite and two with its claws.

Bite. Melee Attack Roll: +18, reach 15 ft. Hit: 21 (2d10 + 10) Piercing damage plus 13 (2d12) Radiant damage plus 9 (2d8) Slashing damage plus 7 (1d12) Radiant damage

Claw. Melee Attack Roll: +18, reach 10 ft. Hit: 19 (2d8 + 10) Slashing damage plus 9 (2d8) Slashing damage plus 7 (1d12) Radiant damage

Tail. Melee Attack Roll: +18, reach 20 ft. Hit: 21 (2d10 + 10) Bludgeoning damage plus 6 (1d10) Slashing damage plus 9 (2d8) Radiant damage.  If the target is a creature, it must succeed on a DC 26 Strength saving throw or be knocked prone.

Frightful Presence. Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 23 Wisdom saving throw or become frightened 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. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.

Rage of the Ultimate Blue-Eyed Dragon (1 Legendary Resistance). Blue Eyes Alternative Ultimate Dragon can choose to spend one charge of its Legendary Resistance to unleashes a concentrated blast of the divine draconic energy flowing through it from each of its three heads against three separate targets it can see within range of its breath attack.  Each target makes a DC 26 Dexterity saving throw, taking 99 (6d12 + 60) Force damage on a failure and half as much on a success.  If this damage reduces the target to 0 Hit Points, it and everything nonmagical it is wearing and carrying are disintegrated into gray dust. For magic items with a rarity below Very Rare, roll a d100.  On a 0-50, the magic item is disintegrated as well. The target can be revived only by a True Resurrection or a Wish spell.

When the Blue Eye Alternative Ultimate Dragon uses this ability, it can no longer take any additional Legendary Actions, or Reactions and its Movement Speed is reduced to 0 until the start of its next turn.
