Reflective Step. The Mirror Man can move between reflective surfaces within 60 feet as if they were adjacent spaces. This movement does not provoke opportunity attacks. It can also make melee weapon attacks through reflective surfaces as if the surface were an extension of itself. However, it can only attack this way if it is within 5 feet of another reflective surface.

Mirror Latch. The Mirror Man can attach itself to a creature’s reflection. The target must make a DC 17 Constitution saving throw. On a failure, the creature is unaware that the Mirror Man has latched onto its reflection. On a success, the creature notices the attempt, and the Mirror Man fails to latch on.

While latched onto a creature, the Mirror Man exists within its reflection, appearing as a subtle distortion or fully replacing the reflection. While latched, the Mirror Man no longer needs to be inside a reflective surface or the Material Plane. If the Mirror Man appears in multiple reflections at once, these are only illusions—it does not create duplicates of itself. Shattering the reflection it inhabits forces it out due to Mirror Demiplane.

Shatter Weakness. If the Mirror Man is hit by the shatter spell, it takes double damage and loses its Reflective Step ability until the end of its next turn.

Shatter Death. When the Mirror Man is reduced to 0 hit points, it shatters in a 5-foot-radius explosion. Each creature in the area must make a DC 17 Dexterity saving throw, taking 10 (3d6) slashing damage on a failure, or half as much on a success.

Mirror Demiplane. While inside a reflective surface or latched onto a creature's reflection, the Mirror Man is considered to be in its Mirror Demiplane. Unless occupying a reflection, it cannot interact with, see, or exist outside of this plane. The Mirror Demiplane is an endless void filled with reflective surfaces.

If the Mirror Man uses a reflection as a gateway, it can interact with and even emerge into the Material Plane. While in its Demiplane, it has resistance to all physical damage except bludgeoning. If the reflective surface it inhabits is shattered, the Mirror Man is forced into the Material Plane, and any active Mirror Latch effects end.

Distorted Image. While within 5 feet of a reflective surface, the Mirror Man imposes disadvantage on attack rolls against it that rely on sight.

Immutable Form. The Mirror Man is immune to any spell or effect that would alter its form.

Magic Weapons. The Mirror Man’s weapon attacks are magical.

Reflective Surface. When targeted by magic missile, a line spell, or a ranged spell attack, roll a d6. On a 6, the spell is reflected back at the caster as though it originated from the Mirror Man.

Multiattack. The Mirror Man makes two Slashing Claw attacks.

Slashing Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target.
Hit: 13 (2d8 + 4) slashing damage plus 7 (2d6) psychic damage.

Gaze of the Abyss. The Mirror Man targets one creature it can see within 60 feet that isn't blind and can see the Mirror Man. The target must make a DC 17 Wisdom saving throw. On a failure, it becomes frightened for 1 minute. A frightened target repeats the saving throw at the end of each of its turns.

 Reflection Shift. When the Mirror Man takes damage, it can use its bonus action to shift into a nearby reflection within 10 feet, reducing the damage taken by 1d10 + its Dexterity modifier. It can only do this if there is a reflection within 10 feet of the Mirror Man

The Mirror Man can take 2 legendary actions, choosing from the options below. 

• Reflective Slash.(Costs 1)T he Mirror Man makes a Slashing Claw attack against a creature.
• Vanishing Step.(Costs 1) The Mirror Man moves up to half its speed without provoking opportunity attacks. It can only use this movement if it moves through a reflective surface at least once.
