Staff of Poison

The Staff of Poison was the weapon of Rahkshi Lerahk. It was created along with it. Its tip could poison anything it came in contact with, causing it either to die or become violent to allies.

Example Usage
In BIONICLE: Mask of Light, Lerahk used it on Tahu Nuva, which caused his mask to slowly become infected; the power of Kurahk's staff caused this infection to spread across his entire mask, turning him violent.
