Bracers of the blinding strike

Bracers of Blinding Strike are a pair of magical bracers worn on the wrists. They allow the wearer's hands to move at roughly twice their normal speed as per a Haste spell. However, unlike the typical benefits granted by that spell, they do not increase the speed at which the wearer's mind functions, a weakness that was exploited by Drizzt Do'Urden in his battle with Dantrag Baenre. The latter was unable to improvise during combat and was forced to stick to rote, practiced combinations, allowing Drizzt to gain the upper hand.
