High Crit (A high crit weapon deals more damage when you score a critical hit with it. A critical hit deals maximum weapon damage and an extra 1[W] at 1st–10th levels, an extra 2[W] at 11th–20th levels, and an extra 3[W] at 21st–30th levels. This extra damage is in addition to any critical damage the weapon supplies if it is a magic weapon.).
Off-Hand (An off-hand weapon is light enough that you can hold it and attack effectively with it while holding a weapon in your main hand. You can’t attack with both weapons in the same turn, unless you have a power that lets you do so, but you can attack with either weapon.).

Light blade (Light blades reward accuracy as much as force. Pinpoint attacks, lunges, and agile defenses are the strong points of these weapons.).
