Sul'thraze the Lasher

Sul'thraze the Lasher, the Splitblade of Suffering, is a two-handed sword.

Prior to Patch 4.0.3a, this item required level 50, which caused it to be commonly skipped over for items such as Ice Barbed Spear. With it now requiring level 44, this item now much more practical for both PvP and leveling.

This also rewards the achievement Sul'thraze the Lasher (achievement).

Background
Weegli Blastfuse, Trenton Lighthammer and Mazoga were searching for the sword.

Source
Sul'thraze the Lasher is created by combining two rare swords from Zul'Farrak, Jang'thraze the Protector and Sang'thraze the Deflector, using Call of Sul'thraze.
