State: open

Description:
"Chance on hit: Blasts your enemy with lightning, dealing 300 Nature damage and then jumping to additional nearby enemies. Each jump reduces that victim's Nature resistance by 25. Affects 5 targets. Your primary target is also consumed by a cyclone, slowing its attack speed by 20% for 12 sec."

So it should affect 5 targets with the nature damage. Currently it only affects your target, the other jumps only get the -25 NR debuff. This is why this weapon was least desirable for twins (jumps to bugs) on retail.
