Krelm's Buff Bracers are a Bracers piece of the Krelm's Buff Bulwark set in Diablo III. They drop at character level 70, and originally only dropped during the Season One for Seasonal characters. After the end of the Season One, they drop for normal characters as well. It is one of the few set items with a Legendary unique affix. These bracers make the character entirely immune to all forms of Stun and Knockback (but not to the damage of hits that would inflict this hit), even to the Vortex affix of the Elite Monsters.
