Brot the Timeless

Double Time (Recharges after a Short or Long Rest). If Brot is reduced to 0 hit points, he doesn’t die or fall Unconscious. Instead, he escapes through a time fracture and simultaneously returns with full hit points. Brot accelerates his local flow of time, which doubles his available actions, bonus actions, reactions, and movement each turn. Additionally, Brot can now use the options in the “Mythic Actions” section. Award a party an additional 155,000 XP (310,000 XP total) for defeating Brot after he uses this trait.

Timeless Nature. Brot doesn't need sleep, air, food, or water, can't be aged magically or suffer effects of old age, and is immune to magical effects that would manipulate time (such as Slow and Time Stop).

Mantle of the Ancient Empire. While Brot wears the Mantle of the Ancient Empire, he has +2 on all saving throws (included above), difficult terrain doesn't cost him extra movement, magic can't reduce his speed or cause him to sleep, and he is immune to the Paralyzed, Restrained, and Grappled conditions (included above), and immune to magic that would detect his location, read his thoughts, know if he is lying or his alignment or creature type, and creatures cannot telepathically communicate with him.

Legendary Willpower (Recharge 5–6). If Brot fails a saving throw, he can choose to succeed instead.

Exceptional Skill. Once per turn, Brot can reroll one failed attack roll, ability check, and saving throw each, and must use the new result.

Evasive. When Brot is subjected to an effect that allows him to make a Dexterity saving throw to take only half damage, he instead takes no damage if he succeeds on the saving throw, and only half damage if he fails.

Elusive. No attack roll against Brot can have Advantage while he isn't Incapacitated.

Mobile. When Brot makes a melee attack against a creature, he doesn't provoke Opportunity Attacks from that creature for the rest of the turn, whether he hit or not.

Deathly Assassin. Brot has Advantage on attack rolls against any creature that hasn't taken its turn in combat. Any hit he scores against a creature that is surprised or has the Incapacitated, Paralyzed, or Restrained conditions is a critical hit and it must succeed on a DC 20 Constitution saving throw or take double damage from the hit.

Sneak Attack. Once per turn, Brot can deal an extra 35 (10d6) damage to one creature he hit with an attack if he has Advantage on the attack roll, or if another enemy of the target is within 5 ft. of it (including copies of himself), that enemy isn’t Incapacitated, and Brot doesn't have Disadvantage on the attack roll.

Multiattack. Brot makes four attacks with his scimitars Platinum Fang and Spellrazor, daggers, and unarmed strikes in any combination.

Platinum Fang. Melee Weapon Attack: +17 to hit, reach 5 ft., one target. Hit: 19 (2d10 + 8) slashing damage. If the target isn't a construct or undead, the hit deals an extra 11 (2d10) necrotic damage and Brot regains hit points equal to the necrotic damage. If the target has fewer than 25 hit points, it must succeed on a DC 20 Constitution saving throw or be slain instantly. If Brot rolls a 20 on the attack roll, the hit also cuts off one of the creature's limbs (if applicable).

Spellrazor. Melee Weapon Attack: +17 to hit, reach 5 ft., one target. Hit: 19 (2d10 + 8) slashing damage, and deals an extra 11 (2d10) damage against inherently magical creatures. Attack rolls ignore magical resistance and defenses (such as Mage Armor and Shield), damage from this weapon ignores resistance and immunity to non-magical weapons, and magical effects cannot modify its attack roll or damage.

Dagger, +3. Melee or Ranged Weapon Attack: +17 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 19 (2d10 + 8) piercing damage if melee, or 24 (2d10 + 2d4 + 8) piercing damage if ranged. Attacking at long range doesn't impose Disadvantage on Brot's ranged weapon attack rolls and his ranged weapon attacks ignore half cover and three-quarters cover. He can choose to take a -5 penalty to a ranged attack roll to add +10 to the attack's damage.

Unarmed Strike. Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 10 (1d10 + 5) bludgeoning (fist/kick/elbow/tail), piercing (bite), or slashing (claws) damage, and the target must succeed on a DC 21 Constitution saving throw or be Stunned until the end of Brot's next turn.

Invisibility. While wearing the Mantle of the Ancient Empire, Brot can turn invisible as an action and remain invisible for 1 minute, until the mantle is removed, until he attacks or casts a spell, or uses a bonus action to become visible again.

Disguise Self. While wearing the Mantle of the Ancient Empire, Brot can cast Disguise Self (detect DC 20) as an action.

Perfect Stillness of Mind. At the beginning of Brot's turn, if any effects are causing him to be Incapacitated, Stunned, Charmed, or Frightened, he automatically expends his action to end these effects on himself.

Perfect Cunning. Brot can Dash, Disengage, Dodge, or Hide, difficult terrain doesn't cost him extra movement, and his jump distance is doubled for the turn (from 15 ft. to 30 ft.).

Flying Blade. While wielding Platinum Fang, Brot can throw the weapon and attack one creature of his choice within a 60 ft. range. After attacking it, the weapon immediately returns to him.

Quick Invisibility. While wearing the Mantle of the Ancient Empire, Brot can turn invisible until the start of his next turn, or until the mantle is removed, or until he attacks or casts a spell.

Ki Sense. Brot gains truesight with a 200 ft. radius until the start of his next turn.

Perfect Parry. Trigger: Brot would be hit by a weapon attack. Response: Brot adds a bonus to his AC against that attack, with a +3 bonus while unarmed, +6 bonus while wielding one weapon, and +9 bonus while wielding two weapons. If the attack misses, he can make an attack against the triggering creature with Advantage.

Uncanny Deflection. Trigger: Brot would be damaged by a weapon attack. Response: Brot attempts to deflect the attack, which reduces its damage by 36 (2d10 + 25). If he reduces damage to 0, he can deflect it toward a creature to make a weapon attack with +14 to hit and a range of 20/60 which deals damage equal to the reduced damage on hit.

Spellraze. Trigger: Brot would be affected by a spell or magical effect while wielding Spellrazor. Response: Brot cuts through the magic with Spellrazor and makes a melee attack roll against the caster's attack roll or save DC. On a success, he negates the effect for himself (area or multi-target effects may still affect others).

Sentinel Strike. Trigger: A creature within 5 ft. of Brot makes an attack against a target other than him. Response: Brot makes a melee weapon attack against the attacking creature. On a hit, the creature's speed becomes 0 for the rest of the turn. Creatures provoke Opportunity Attacks from Brot even if they take the Disengage action.

Perfect Landing. Trigger: Brot would take fall damage. Response: Brot negates all fall damage.

Brot can take 5 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. Brot regains spent legendary actions at the start of his turn.

Ready Response. Brot recovers one reaction.

Quick Strike. Brot moves up to 35 ft. and makes an attack (preferably with Platinum Fang).

Bonus Action. Brot can make one of his bonus actions listed above.

If Brot's Double Time trait is active, he can use the options below as legendary actions.

Time Walk. Brot moves through time, and returns to the present in an unoccupied space of his choice.

Time Attack (Costs 2 Actions). A copy of Brot emerges from the future in an unoccupied space and makes an attack. After attacking, the copy immediately moves through time and disappears.

Time Copy (Costs 3 Actions). A copy of Brot emerges from the future in an unoccupied space and makes an attack. The copy shares his initiative and turn order, and takes his turn immediately before the present Brot. At the end of present Brot's next turn, he moves through time and disappears, and the copy becomes the present Brot.
