You can use an action to dismiss them.
Each time you're targeted by a creature's attack, roll a d20 to see if it targets you or one of your copies.
With 3 copies, a roll of 6 or higher means a copy is targeted. With two copies, a roll of 8 or higher targets a copy, and with 1 copy a roll of 11 or higher targets the copy.
A copy's AC is 10 + your Dexterity modifier, and when it is hit by an attack a copy is destroyed.
It may be destroyed only by an attack that hits it.
All other damage and effects have no impact.
Attacking creatures that have truesight, cannot see, have blindsight, or rely on other nonvisual senses are unaffected by this spell.
