Grip of Kulemak

For some reason the Grip of Kulemak ring even though it is a unique ring with these stats :
Faster start of energy shield recharge rate
Reduced presence area of effect
Reduced light radius
Increased magnitude of abyssal wasting you inflict
Increased area of effect for attacks

This ring will not go into the ring tab of the uniques tab folder.
