Aura of Weakness. Any creature who tries to attack
the revenant with a weapon attack that uses Strength
must make a DC 15 Constitution saving throw. On a
failed save that attack deals only half damage.
Regeneration. The revenant regains 10 hit points at
the start of its turn. If the revenant takes fire damage,
this trait doesn't function at the start of the
revenant's next turn. The revenant's body is
destroyed only if it starts its turn with 0 hit points
and doesn't regenerate.

Spike. As a bonus action the revenant can make a
longsword attack against a prone target, dealing an
extra 21 (6d6) damage to the target if the attack is
successful.
Actions
Multiattack. The revenant makes three melee attacks.
Alternatively it can use its pull ability and make a
longsword attack.
Longsword. Melee Weapon Attack: +9 to hit, reach
5ft., one target. Hit: 9 (1d10 + 5) slashing damage, or
10 (1d12 + 3) slashing damage if used with two
hands.
Shield Bash. Melee Weapon Attack: +9 to hit, reach
5ft., one target. Hit: 7 (1d4 + 5) bludgeoning
damage. If the target is Large or smaller, it must
succeed on a DC 15 Strength saving throw or be
knocked prone.
Fade Pull. The revenant targets one creature it can see
within 60 feet. The target must make DC 15 Strength
saving throw or be pulled through thin air to an
unoccupied space beside the revenant, ignoring any
obstructions in its path.

Reactions
Parry. The revenant adds 3 to its AC against one
melee attack that would hit it. To do so, the revenant
must see the attacker and be wielding a melee
weapon.
