Double scimitar - secondary end
Superior double melee weaponDamage
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.
