I'm on the Edge of Greed [3.5 Weapon]
Edge of Avarice
The edge of avarice is a golden cutlass with emeralds, rubies, diamonds, and sapphires set in its hilt and pommel, making it look rather ridiculous and obviously expensive. Whenever the blade is near something valuable that the wielder or the wielder's allies do not possess, it glows brightly, golden light shining from its blade and its gems reflecting light based on their colors.
The edge of avarice is a +5 keen cutlass that glows brightly whenever within 30 feet of a valuable object or sum of money (worth 400 or more gold pieces), shedding light as a torch until the object or money is in the wielder's or in his allies' hands or until the edge of avarice is sheathed, at which point the blade sheds a negligible amount of light. In addition, whenever the wielder succeeds in downing a worthy foe with the edge of avarice (by either reducing its hit points to 0 or killing it), the wielder gains a number of gold pieces equal to ten times his level, transforming the creature's lifeblood into a stream of gold that hardens into coins after a few seconds. A worthy foe is one that is of an equal CR or higher. The wielder must be the one that brings the foe down.
