Bracers of the blinding strike
From Forgotten Realms Wiki
This pair of magical ringlets can be worn over any appendage, size permitting to magically increase the speed of, in most cases the limb which the ringlet adorns. Therefore being referred to more commonly as 'bracelets' or 'anklets'.
The dark elf Drizzt Do'Urden wore the ringlets over his wrists to increase his attack speed, however due to the sudden lunging of his lightning quick attacks he soon realised they restricted and hampered his ability to adapt and improvise during any particular strike or defensive block whereas normally he could change the direction, speed and angle mid-movement.
Switching the ringlets to his ankles has given him increased speed and dashing footwork which has proved far more beneficial in his melee fighting style, allowing him to run literal 'circles' around his foes.
