A mandate of execution has been placed upon your target, granting you X Haste. Your strikes against your victim grant you stacking Critical Strike.
Mark your target for execution, increasing your Haste by 1.2003 × SP for 20 sec. While the target is marked, each of your attacks against them grants an additional 0.0857 × SP Critical Strike, as the Void urges you to finish the kill, up to a maximum of X Critical Strike.
