Mirror Image

2nd-Level Illusion
Casting Time: 1 action
Range: Self
Components: VS
Duration: 1 minute

Three illusory duplicates of yourself appear in your space. Until the spell ends, the duplicates move with you and mimic your actions, shifting position so it's impossible to track which image is real. You can use your action to dismiss the illusory duplicates.

Each time a creature targets you with an attack during the spell's duration, roll a d20 to determine whether the attack instead targets one of your duplicates.

If you have three duplicates, you must roll a6 or higher to change the attack's target to a duplicate. With two duplicates, you must roll an 8 or higher. With one duplicate, you must roll an 11 or higher.

A duplicate's AC equals 10 + your Dexterity modifier. If an attack hits a duplicate, the duplicate is destroyed. A duplicate can be destroyed only by an attack that hits it.

It ignores all other damage and effects. The spell ends when all three duplicates are destroyed.

A creature is unaffected by this spell if it can't see, if it relies on senses other than sight, such as blindsight, or if it can perceive illusions as false, as with truesight.

At Higher Levels. When you cast this spell using a spell slot of 4th or 5th level, the duration is 10 minutes. When you cast this spell using a spell slot of 6th or 7th level, the duration is 1 hour. When you cast this spell using a spell slot of 8th level or higher, the duration is 8 hours.
