got my Void Exotic sword last week. only thing i had done with the solar and arc swords was get the 50 yellow bar PVE enemy kills. played about 4 hours yesterday (titan) and 6 hrs today (hunter) and now both solar and arc are waiting for the weekly reset - then the darkblade strike. the titan was super easy (solar). used the perk that every melee kill instantly restores full melee ability. bad juju for added super recharge energy. the hunter (arc) was painful. it was only 2 more hours, but it was a struggle. used monte carlo for melee recharge .
