Revenant

Multiattack.

The revenant makes two attacks.

Vengeful Glare.

The revenant targets one creature it can see within 30 feet of it and against which it has sworn vengeance. The target must make a DC 15 Wisdom saving throw. On a failure, the target is paralyzed until the revenant deals damage to it, or until the end of the revenant’s next turn. When the paralysis ends, the target is frightened of the revenant for 1 minute. The frightened target can repeat the saving throw at the end of each of its turns, with disadvantage if it can see the revenant, ending the frightened condition on itself on a success.

Hunger for Revenge.

A revenant has only one year to exact revenge. When its adversary dies, or if the revenant fails to kill its adversary before its time runs out, it crumbles to dust and its soul fades into the afterlife. If its foe is too powerful for the revenant to destroy on its own, it seeks worthy allies to help it fulfill its quest.

Divine Justice.

No magic can hide a creature pursued by a revenant, which always knows the direction and distance between it and the target of its vengeance. In cases where the revenant seeks revenge against more than one adversary, it pursues them one at a time, starting with the creature that dealt it the killing blow. If the revenant's body is destroyed, its soul flies forth to seek out a new corpse in which to resume its hunt.

Vengeful Tracker.

The revenant knows the distance to and direction of any creature against which it seeks revenge, even if the creature and the revenant are on different planes of existence. If the creature being tracked by the revenant dies, the revenant knows.

Undead Nature.

A revenant doesn't require air, food, drink, or sleep.

Barbarian

Rage

In battle, you fight with primal ferocity. On your turn, you can enter a rage as a bonus action.

While raging, you gain the following benefits if you aren't wearing heavy armor:

You have advantage on Strength checks and Strength saving throws.
When you make a melee weapon attack using Strength, you gain a bonus to the damage roll that increases as you gain levels as a barbarian, as shown in the Rage Damage column of the Barbarian table.
You have resistance to bludgeoning, piercing, and slashing damage.
If you are able to cast spells, you can't cast them or concentrate on them while raging.

Your rage lasts for 1 minute. It ends early if you are knocked unconscious or if your turn ends and you haven't attacked a hostile creature since your last turn or taken damage since then. You can also end your rage on your turn as a bonus action.

Once you have raged the number of times shown for your barbarian level in the Rages column of the Barbarian table, you must finish a long rest before you can rage again.

Unarmored Defense

While you are not wearing any armor, your armor class equals 10 + your Dexterity modifier + your Constitution modifier. You can use a shield and still gain this benefit.

Danger Sense

You gain an uncanny sense of when things nearby aren't as they should be, giving you an edge when you dodge away from danger. You have advantage on Dexterity saving throws against effects that you can see, such as traps and spells. To gain this benefit, you can't be blinded, deafened, or incapacitated

Reckless Attack

You can throw aside all concern for defense to attack with fierce desperation. When you make your first attack on your turn, you can decide to attack recklessly. Doing so gives you advantage on melee weapon attack rolls using Strength during this turn, but attack rolls against you have advantage until your next turn.

Extra Attack

You can attack twice, instead of once, whenever you take the Attack action on your turn.

Fast Movement

Your speed increases by 10 feet while you aren't wearing heavy armor.

Feral Instinct

Your instincts are so honed that you have advantage on initiative rolls.

Additionally, if you are surprised at the beginning of combat and aren't incapacitated, you can act normally on your first turn, but only if you enter your rage before doing anything else on that turn.

Instinctive Pounce

As part of the bonus action you take to enter your rage, you can move up to half your speed.

Brutal Critical

You can roll one additional weapon damage die when determining the extra damage for a critical hit with a melee attack.

Frenzy

You can go into a frenzy when you rage. If you do so, for the duration of your rage you can make a single melee weapon attack as a bonus action on each of your turns after this one. When your rage ends, you suffer one level of exhaustion.

Mindless Rage

You can't be charmed or frightened while raging. If you are charmed or frightened when you enter your rage, the effect is suspended for the duration of the rage.
