[Sacrificial Steel] requires an extra Forma and only out performs [Gladiator Might] or a Smite mod by a small margin. This build is meant for use with a 800+ Power [Wisp] and, therefore, skips on the additive bonus from an Attack Speed mod. [Berserker Fury] can replace [Primed Reach] or [Sacrificial Steel] when used without a [Wisp].

Riven would likely be better with Combo Duration or Critical Damage instead of the small boost to Range. Finisher Damage or Heavy Attack Efficiency would be ideal Curses for the Riven.
