Temporal Echo

You fracture across time. Echoes of yourself flicker at the edges of memory. You summon an Echo when casting a time-based spell. When you cast a spell of 1st level or higher that affects time (e.g. Slow, Haste, Hold Person, Time Stop), you create an Echo of yourself that lasts until the start of your next turn.

This Echo occupies a 5-ft space adjacent to you and mirrors your appearance.

As a reaction when targeted by an attack, you may swap places with your Echo, causing the attack to target the Echo instead. The Echo has AC 10 and vanishes when hit.

Once per long rest, you may choose to recast your last spell (of 2nd level or lower) without expending a spell slot, as your Echo finishes what you began.
