Temporal Echo

You bend the weave to cast an echo of yourself or another through time. For the duration of the spell whenever the recipient of this enchantment takes an action, it is made again by the echo without expending resources. The spell can only replay actions that take place after it is cast and the echo happens immediately following said action once per turn. Bonus actions that happen simultaneously to actions are also copied like the Paladins Smite for example. The echo can only cast spells up to one level below the level to cast this enchantment and if the spell has a target; the echo targets the same thing. New rolls for attacks and saves must be made if applicable and the spell save DC and attack modifier for the echo are the same as the attackers. Reactions also trigger the echo. Due to the stress this ability imposes on the recipient this spell can only be cast on same creature once per long rest.

At higher levels Increase the spell level cap for the echo and for every 2 levels increase the duration by 1 turn.
