If I vault someone with a spear...which in turn is my unholy weapon, and then I change to a sword for melee; and they flee and get away...I then wield my unholy spear again, and they die from bleeding...will I still get a charge if they are worth anything? I was just wondering if I had to wield my unholy throughout the battle to get the charge on that weapon?

Another question is if I have two unholy weapons...and I vault...then wield an unholy blessed sword...and kill them with the sword...will I get the charge or must the charge be with the weapon with initial damage?
