Dead Ringer

After taking damage from any source, you become invisible. Anything you are wearing or carrying becomes invisible as long as it’s on your person. Simultaneously, an illusory duplicate of you goes limp from the exact position in which you took the damage. This copy will fall and collide with its environment, but it has no mass and any creatures or weapons that touch it will pass through it. An Intelligence (Investigation) check that beats your spell save DC must be made to detect the illusion without making contact with it.

The spell ends at the end of your next turn, or if you attack or cast a spell. The duplicate dissipates when the spell ends.
