If you get hit by a Critical hit, there's a chance for this perk to reduce its damage and prevent you from falling to the ground. Obviously, the anti-knockback will not work if you're airborne or already laying on the ground, but the damage reduction will still work regardless.

And do you know that Rock works well in compliment with Legion's uninterruption? Rock can prevent Criticals from cancelling the uninterruption, therefore allowing you to continue your ongoing attack.
