Can I make a extra melee attack with Harmony Blade and Two-Weapon Opening and Rampage on the same crit?
If I crit again with Rampage can I again make a melee attack with harmony blade and two weapon opening?
Rampage[DDI]: Barbarian class feature - once per round, when you score a critical hit with a barbarian attack power, you can immediately make a melee basic attack as a free action, you do not have to attack the same target that you scorred a critical attack against
Harmony Blade[DDI]: from item set Blade Dancer's Regalia - Critical: +1D6 damage per plus, and you can make a melee basic attack with your off-hand weapon.
Two-weapon Opening[DDI]: paragon feat from the two-weapon fighting chain - when you are wielding two melee weapons and you score a critical hit with your main weapon, you can make a melee basic attack with your off-hand weaponagainst the same target as free action. (PHB2)
