You wreathe strands of time around your body, copying the moment the attack or spell affects you. You are affected by the attack or spell as normal. At the start of your next turn, a copy of the attack or spell reflects back at the attacker or spellcaster, using the attack roll, spell DCs, and similar statistics of the original attack or spell. If the creature that made the triggering attack or cast the triggering spell is no longer a valid target, such as if it died or if it is out of range, the copied attack or spell fails.
