Magic Resistance. The Enigmirror has advantage on saving throws against spells and other magical effects.

Spell Reflection. If the Enigmirror makes a successful saving throw against a spell, or a spell attack misses it, the Enigmirror can choose another creature (including the spellcaster) it can see within 60 feet of it. The spell targets the chosen creature instead of the Enigmirror. If the spell forced a saving throw, the chosen creature makes its own save. If the spell was an attack, the attack roll is rerolled against the chosen creature.

Telepathic Bond. The Enigmirror ignores the range restriction on its telepathy when communicating with a creature it deems as an ally. The two don't even need to be on the same plane of existence.

Shielded Mind. The Enigmirror is immune to scrying and to any effect that would sense its emotions, read its thoughts, or detect its location.

Tainted Magic. The Enigmirror's spells can be unsafe for mortals. Under the DM's discretion, each time the Enigmirror casts a spell the closest creature must make a DC 18 Wisdom save or be cursed for 1d4 days. Example curses include:

• Emotibow Curse Your shifting skin color betrays your emotional state.
• Piper’s Parade Curse You attract a parade of vermin wherever you go.
• Shrinkwrap Curse You shrink and become Small size. If you are already small, you become Medium Size.
• Friend of Fabric Curse You can speak to clothing, and they won't shut up.
  
• Language Flipper Curse The languages you know, including common, are randomly rerolled into new languages.
• Gender-Bender Curse You awaken the next day as the opposite sex.

Spellcasting. The Enigmirror is an 18th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 17, +9 to hit with spell attacks). The Enigmirror can cast dream and Far Step at will and can innately cast the following spells, requiring only somatic components:

Cantrips (at will): guidance, light, mage hand, prestidigitation, minor illusion

1st level (4 slots): detect magic, identify, mage armor, magic missile

2nd level (3 slots): detect thoughts, mirror image, misty step

3rd level (3 slots): create food and water, fly, conjure animals

4th level (3 slots): banishment, polymorph, arcane eye

5th level (3 slots): awaken, scrying, animate objects

6th level (1 slot): scatter

7th level (1 slot): teleport

8th level (1 slot): animal shapes

9th level (1 slot): time stop

Psychic Projection. Each creature within 60 feet of the Enigmirror must make a DC 17 Wisdom saving throw, taking 15 (2d10 + 4) psychic damage on a failed save, or half as much damage on a successful one.

Change Shape. The Engimirror magically polymorphs into a humanoid or beast that has a challenge rating equal to or less than its own, or back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed or borne by the new form (the Enigmirror's choice).

In a new form, the Enigmirror retains its game statistics and ability to speak, but its AC, movement modes, Strength, Dexterity, and other actions are replaced by those of the new form, and it gains any statistics and capabilities (except class features, legendary actions, and lair actions) that the new form has but that it lacks. If the new form has a bite attack, the Enigmirror can use its bite in that form.
