When this 4-foot-tall mirror is viewed indirectly, its surface shows faint images of creatures. The mirror weighs 50 pounds, and it has AC 11, 10 hit points, and vulnerability to bludgeoning damage. It shatters and is destroyed when reduced to 0 hit points.
If the mirror is hanging on a vertical surface and you are within 5 feet of it, you can use an action to speak its command word and activate it. It remains activated until you use an action to speak the command word again.
Any creature other than you that sees its reflection in the activated mirror while within 30 feet of it must succeed on a DC 15 Charisma saving throw or be trapped, along with anything it is wearing or carrying, in one of the mirror's twelve extradimensional cells. This saving throw is made with advantage if the creature knows the mirror's nature, and constructs succeed on the saving throw automatically.
An extradimensional cell is an infinite expanse filled with thick fog that reduces visibility to 10 feet. Creatures trapped in the mirror's cells don't age, and they don't need to eat, drink, or sleep. A creature trapped within a cell can escape using magic that permits planar travel. Otherwise, the creature is confined to the cell until freed.
If the mirror traps a creature but its twelve extradimensional cells are already occupied, the mirror frees one trapped creature at random to accommodate the new prisoner. A freed creature appears in an unoccupied space within sight of the mirror but facing away from it. If the mirror is shattered, all creatures it contains are freed and appear in unoccupied spaces near it.
While within 5 feet of the mirror, you can use an action to speak the name of one creature trapped in it or call out a particular cell by number. The creature named or contained in the named cell appears as an image on the mirror's surface. You and the creature can then communicate normally.
In a similar way, you can use an action to speak a second command word and free one creature trapped in the mirror. The freed creature appears, along with its possessions, in the unoccupied space nearest to the mirror and facing away from it.

Plan to destroy the book of vial darkness
1. Get book
2. Get this mirror
3. Sacrifice self to mirror with book
4. Kill self
5. Have party cast true resurrection
*Golf Claps*
:D
That wouldn't destroy the book though, given the item description in 5e.
I ment trap it forever
Yeah it's fun.
It only ends in tears
Couldn't someone just get in the same slot as the book, get the book, and get freed? So it would probably keep it trapped for a while but it would probably be freed eventually.
One out of twelve chance for the right one, at that point it is very likely that infighting will occur, weaken the group and then you swoop in and kill them. Also have clones nearby so they can't kill the guards.
I randomly came across this and thought my party would just throw it in their bag of holding to pull out so that they could just use it to throw any enemy I threw at them into it. Like a Poke' Ball. But then I realized. Its an extra-dimensional space. It will kill them all. XD
What happens to the people inside when the mirror is broken?
Nevermind, reread the thingy, they're all freed
“A creature trapped within a cell can escape using magic that permits planar travel.”
I wonder if casting Blink while in one of the cells would let you escape since the spell briefly sends you to the Ethereal Plane.
DM Adjudication? I'd rule "NO," that you needed something stronger than a 3rd-level spell.
I mean, with how blink works it'd send you to the Ethereal Plane when you blink out, and then it'd blink you right back into the mirror.
The “one” and only tarasque be like: hello, me-eeeeee? Aghhhhhhhhhhhhhhhhhhhhhhhhhhhh!
A powerfull mage could use it to study for eternity without aging at all (or almost) by putting it in his library, only going out to acquire new material, having an assistant (or a familiar) freeing him each time.
The Ethereal Plane overlaps the material Plane in most settings I believe, so I think normally you aren't transporting yourself as much as slipping into it, I would imagine its either a similar deal within the cell, or completely inaccessible as you aren't in the material plane
haha, this guy has an eternity to study magic and spends none of it learning spells to get out of his own mirror.
