Cruelondeb, the First Blessed

Gwyneria's Blessing. Blessed by Gwyneira, Cruelondeb gains immunity to cold damage and disease. Additionally, Cruelondeb counts as both a draconic and humanoid creature for the sake of spells and abilities.

Cruelty Knows No Bounds. Cruelondeb has advantage on attack rolls against all creatures that are frightened, or have less than half their remaining hitpoints and are still conscious.

Duplictious Mind. Cruelondeb has advantage on concentration checks. Alternatively, he can concentrate on two different spells at once, having disadvantage on both checks while concentrating on two spells in this way.

Legendary Resistance (4/day). If Cruelondeb fails a saving throw, he can choose to succeed instead.

Saving Face (1/short rest). If Cruelondeb misses with an attack or fails an ability check or saving throw, he can gain a bonus equal to the number of enemies he can see within 30 ft (max +5).

Great Weapon Master. On Cruelondeb's turn, whenever he scores a critical hit with a melee weapon or reduces a creature to 0 hit points with one, he can make one melee weapon attack as a bonus action. Additionally, before he makes a melee attack with a heavy weapon that he is proficient with, he can choose to take a -5 penalty to the attack roll. If the attack hits, he adds +10 to the attacks' damage (included in the attack).

Greataxe of the Greatwyrm. Cruelondeb’s attack with his axe ignores the bonus to armour granted by the Shield. Additionally, if he throws the axe, it returns to his hand immediately regardless of if he hits or misses.

Action Surge (2/Short Rest). Cruelondeb can take one additional action on his turn. He cannot Action Surge twice in the same turn.

Remarkable Athlete. Cruelondeb can add +5 to any Strength, Dexterity, or Constitution check he makes that doesn't already use his proficiency bonus. Additionally, whenever he makes a running long jump, he can add 5ft. to the distance.

Superior Critical. Cruelondeb scores a critical hit on a roll of 18, 19, or 20.

Survivor. Cruelondeb regains 10hp if he has no more than half of his hp remaining. This ability does not function if Cruelondeb is at 0 hp or in his Mythic Phase.

Improved Mage Slayer. When Cruelondeb damages a creature that is concentrating on a spell, that creature has disadvantage on the saving throw to maintain its concentration. Additionally, he has advantage on saving throws against spells 

Alert. Cruelondeb cannot be surprised, and he gains a +5 bonus to initiative.

Sentinel. When Creulondeb hits a creature with an opportunity attack, the creature's speed becomes 0 for the rest of the turn. Creatures provoke opportunity attacks from him even if they take the Disengage action.

Reactive. Cruelondeb may take two reactions each round in combat.

Divine Smite. When Cruelondeb hits with an attack, he can expend one spell slot to deal 2d8 extra radiant damage to the target plus 1d8 for each spell level higher than 1st, plus 1d8 against undead or fiends (max 6d8 total). He cannot smite on critical hits.

Channel Divinity (2/day). Cruelondeb can use channel divinity to power some abilities as noted later in his statblock.

Aura of Protection. While conscious, Cruelondeb gets a +6 bonus to all saving throws.

Metamagic. Cruelondeb can use sorcery points to twist spells to suit his needs as noted later in his statblock. He can only use one metamagic option per spell.

Metamagic: Subtle Spell. When Cruelondeb casts a spell, he can spend 1 sorcery point to cast it without any Somatic or Verbal components.

Metamagic: Quickened Spell. When Cruelondeb casts a spell that has a casting time of 1 action, he can spend 2 sorcery points to change the casting time to 1 bonus action for this casting.

Metamagic: Heightened Spell. When Cruelondeb casts a spell that forces a creature to make a saving throw, he can spend 3 sorcery points to give one target of the spell disadvantage on its first saving throw made against the spell.

Magical Guidance. Whenever Cruelondeb makes an ability check that fails, he can spend 1 sorcery point to reroll the d20. He must use the new roll, even if it is worse.

Prove Your Worth (1/day). The first time Cruelondeb would be reduced to 0 hit points, he instead regains half his hit points (rounded down), all uses of Second Wind, and Action Surge.

Lay on Hands (30hp/day). Cruelondeb can touch a creature to restore any number of HP remaining in the pool, or 5 HP to either cure a disease or neutralize a poison affecting the creature.

Channel Divinity: Abjure Enemies. As an action, Cruelondeb can choose any number of creatures within 60 ft. of him that he can see to make a DC25 Wisdom saving throw. Fiends and undead have disadvantage on this saving throw. On a failure, the creature is frightened and its speed is reduced to 0 (and it can't benefit from bonuses to speed) for 1 minute or until it takes any damage. On success, the creature’s speed is halved for 1 minute or until the creature takes any damage.

Bastion of Law. Cruelondeb can expend up to 5 sorcery points to create a magical ward around himself, lasting until the end of his next long rest. The ward is represented by a number of d8s equal to the number of sorcery points spent to create it. When he takes damage, he can expend a number of those dice, roll them, and reduce the damage taken by the total rolled on those dice.

Glacial Breath (Recharge 5 or 6). Cruelondeb exhales a frigid breath in a 60 ft. cone. Each creature in the area must make a DC 25 Constitution saving throw. Each creature who fails the save takes 39 (6d12) cold damage, and until the end of the creature's next turn, it has a -2 penalty to AC and Dexterity saving throws, and it can't use reactions. On its turn, it can use either an action or a bonus action, not both. Regardless of the creature's abilities or magic items, it can't make more than one melee or ranged attack during its turn. Additionally, if the creature attempts to cast a spell with a casting time of 1 action, it must roll a d20. On an 11 or higher, the spell doesn't take effect until the creature's next turn, and the creature must use its action on that turn to complete the spell. If it can't, the spell is wasted. On a success, a creature takes half damage and suffers no other ill effects.

Channel Divinity: Vow of Enmity. Cruelondeb can choose a creature he can see within 10 ft. of himself and gain advantage on attack rolls against it for 1 minute or until it drops to 0 HP or falls unconscious.

Channel Divinity: Harness Divine Power. Cruelondeb can expend a use of his Channel Divinity to fuel his spells. He regains one expended spell slot of up to 4th level.

Trance of Order. Cruelondeb can align his consciousness to Mechanus, for up to 1 minute. For the duration, while he concentrates on this ability, attack rolls against him can’t benefit from advantage, and whenever he makes an attack roll, an ability check, or a saving throw, he can treat a roll of 9 or lower on the d20 as a 10. Once he uses this bonus action, he can’t use it again until he finishes a long rest, unless he spends 5 sorcery points to use it again. He cannot add the aura of protection bonus to concentration saves to maintain this ability.

Improved Mage Slayer. When a creature within range of one of Cruelondeb's attacks casts a spell, he can use his reaction to make an attack against that creature.

Restore Balance (8/day). When a creature Cruelondeb can see within 60 feet of him is about to roll a d20 with advantage or disadvantage, he can prevent the roll from being affected by advantage and disadvantage.
