This enchantment requires the wielder is at least level 75.
The enchant procs about 5% of the time and lasts for 10 seconds. If you parry during this time, the enchant will cause damage. If the enchant procs again during the 10 seconds, it will refresh and stack, up to 5 times. Stacking up 5 would be exceedingly rare given the chance to proc. If you do not parry in the 10 second time frame, no matter how many stacks you have accumulated, the effect dispels.
