Tuesday Terror: Mirror Ghost
Today, the Tuesday Terror returns with a vengeance.
The mirror ghost (also called Bloody Mary) seeks to visit terrible vengeance on the living, but it is seldom encountered, as it exists in Vioo, the barren, dark realm that exists on the other side of mirrors and mirror-like surfaces (which form the only passages through which light passes into Vioo). The mirror ghost can only affect the Material Realm when summoned.

Conditional Invisibility. On the Material Plane, the mirror ghost is invisible except for its reflection. A creature can target the mirror ghost via its reflection, but ranged attacks made this way have disadvantage.
Incorporeal Movement. The mirror ghost can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.
Mirror Sight. The mirror ghost can see 60 feet into the Material Plane when it is in Vioo, and vice versa.
Mirror Travel. Once summoned the Material Plane, the mirror ghost, on its turn, can use 10 feet of its movement to step magically into one reflective surface within its reach and emerge from a second reflective surface within 60 feet of the first reflective surface, appearing in an unoccupied space within 5 feet of the second reflective surface. Both surfaces must be Small or larger.
Actions
Withering Touch. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 18 (4d6+4) necrotic damage.
Bane (Recharges after a Short or Long Rest). The mirror ghost can curse up to three creatures of its choice that it can see within 30 feet. Each creature must make DC 16 Charisma saving throw. For 1 minute whenever a target that fails this saving throw makes an attack roll or a saving throw, the target must roll a d4 and subtract the number rolled from the attack roll or saving throw.
Summoning Chant (Recharge 6). While in Vioo, the mirror ghost can compel a living creature that sees its own reflection from no farther away than 60 feet and behind which the mirror ghost hides. The creature must succeed on a DC 16 Charisma saving throw or be rooted to the spot and compelled to say the mirror ghost’s name once per turn for three turns. During this time, the creature is restrained. At the start of the creature’s turn, it must use its bonus action to speak aloud the mirror ghost’s name. The target can repeat the saving throw with disadvantage at the end of each of its turns, ending the effect on itself on a success. The target is immune to this mirror ghost’s Summoning Chant for 24 hours after succeeding on the saving throw. The mirror ghost can enter the Material Plane on its turn after the third time its name is spoken by a creature. The mirror ghost can remain on the Material Plane for no more than 24 hours.
