This bladed weapon is almost transparent when drawn, and the blade seems to crawl with visages of screaming faces that writhe and cross it's surface.
Property: +1 / +2 / +3 to attack per tier.
Soulcatcher: (Daily) If your attack kills your foe, you can choose (as a free action) to have the blade scream audibly - ripping a part of of your enemy's spirit free before it can be damaged. Note how much extra damage past 0 hit points you caused, and apply that amount to your next attack that hits. If you do not hit before the end of the battle, then that damage is taken by the wielder as the soul-energy is siphoned off.
Quirk: During quiet moments, stares vacantly at apparently nothing until interrupted.
