Broken Mirror Army

You conjure 12 mirror-soldiers, shimmering silhouettes of yourself armed with gleaming glass spears. They appear in a formation around a point you can see. On your turn, you can command them (no action) to:

• Form a 20-foot-long wall of illusion: creatures cannot see or move through without succeeding on an Intelligence saving throw.

• Attack in unison: choose up to 3 targets within 60 feet. Each must succeed on a Dexterity saving throw or take 4d6 psychic damage, as the mirror-soldiers will seemingly teleport to their targets.

They vanish if they take damage or interact physically with anyone.
