Fractured Soul Echo

You can momentarily become semi-ethereal, flickering between timelines.

Once per short rest, when you are hit by an attack, you can use your reaction to turn incorporeal until the start of your next turn. While incorporeal, you gain resistance to all damage except force, psychic, and radiant.

You leave behind a glowing echo that mimics your pose before phasing, which fades after 6 seconds.
