If DRK needs anything, it'd be a utility buff. As it is right now, Delirium is about a step and a half above useless, and reprisal is kinda weird.

Random idea for reprisal: Keep it where it can proc off a parry, but make it so we can chain it off something like Plunge or DA-S&C, which keeps it in its primary purpose, but also lets us have an on-demand OT cooldown.
