Fracture Timeflow

Your ability to interact with and even observe the flow of time allows you to fracture it slightly in a localized place whenever you land a particularly solid blow on a foe. Whenever you achieve a critical success with a Strike, the target of that Strike must also attempt a save against your class DC or spell DC, whichever is higher.

Critical Success The target is unaffected by the fractured timeflow.

Success The target is Slowed 1 for 1 round.

Failure The target is Slowed 2 for 1 round.

Critical Failure The target is Stunned 3, then slowed 2 for 1 round after they recover from being stunned.
