Aura's for weapons. Dual Blades power set would have the option to have different aura's for each weapon and Staff Fighting would have the option for the entire staff to have an aura or just the ends, and there could be an option to have different auras for each end.
Caps need emblems.
Staff Fighting - Pitchfork - There is a trident already, but it's not quite the same look as a pitchfork.
Titan Weapons/Staff Fighting - War Scythe
Battle Axe or Broadsword and Dual Blades- Sickle
New Power set - Polearm - or put it in staff fighting, but I think it fits better as it's own power set.
