The Mirror v2

A mirror serves as this extradimensional force's entry point into this world. At first glance it appears to be an enchanted mirror, with spells for infiltration and espionage, but it seems there's something more to this mirror than mere magical intelligence...

Snow White's going to have a very bad day.

Echo Form

Starting at 1st level, as an action, you create a perfect illusion of yourself that lasts for 1 minute, or until you lose your concentration (as if you were concentrating on a spell). The illusion appears in an unoccupied space that you can see within 30 feet of you. As a bonus action on your turn, you can move the illusion up to 30 feet to a space you can see, but it must remain within 120 feet of you.

For the duration, you can cast spells as though you were in the illusion's space, but you must use your own senses. Additionally, when both you and your illusion are within 5 feet of a creature that can see the illusion, you have advantage on attack rolls against that creature, given how distracting the illusion is to the target.

Once you use this feature, you can't use it again until you finish a short or long rest.

Reflective Reflex

Starting at 6th level, when you are targeted by a spell of a level that you could cast at, you can use your reaction to attempt to reflect the spell. The DC for this check is 10 + the spell's level. On a success, you cast the spell on the caster without using any spell slots or material components. This does not prevent any effects of the spell hitting you.

You can use this feature a number of times equal to your Charisma modifier (minimum: 1). You regain spent uses of this feature after a short rest.

Dimensional Distortion

Starting at 10th level, you can touch a mirror to link it to your own for up to 1 day. As an action, you can use your concentration to transform the mirrors into portals for up to 10 minutes. You can close the portals at will, without using an action. Your mirror can only be linked to one other mirror at a time.

Any creature or object entering the portal exits from the other portal as if the two were adjacent to each other; passing through a portal from the nonportal side has no effect. Objects need not physically fit within the size of either mirror; merely touching the surface of a portal will send an object through, as long as there is sufficient space for it to appear.

You can only open a portal once per short or long rest.

Prismatic Prison

Starting at 14th level, when you hit a creature with an attack, you can force the target to make a Charisma save. The DC for this save is (8 + your Proficiency Bonus + your Charisma modifier). If it fails the save, the target is instantly transported through the space between dimensions, and becomes trapped in a mirror. The creatures disappear into your mirror and take 4d10 force damage. On a successful save, the target takes half damage and suffers no additional effects.

At the end of your next turn and each turn afterwards, a trapped creature can make a Wisdom saving throw. On a successful save, the creature is released from the mirror dimension. On a failed save, the creature continues to remain trapped, and takes an additional 1d10 force damage.

If a creature dies from this damage, it cannot be revived by anything short of a Wish spell.

Once you use this feature, you can't use it again until you finish a long rest.
