Shivering (3.5e Equipment)
From D&D Wiki
Shivering: A Shivering weapon has a ten percent chance to force a target to shiver. When a creature shivers, it wastes a full round action and cannot make any other action that round. The Greater Shivering enhacement funcrions exactly the same, but has a 25% chance for the target to shiver, and costs 8500. On a critical hit, the target automatically shivers. Creatures immune to cold can still shiver.
