soulbound pvp items

[Ven-elexver1]

aye one know how to soul bind a item? Long Long Ago eq pvp had a soulbind item on players looked like a coin you could loot it from the players once you had pk-ed them. The item cant bee seen or Droped by the player . but once he is dead the item is on his corpse and others may loot it . I would like to set a npc quest that could take the coins and players may buy items from said ncp . but sound like it will take more know how than i have at this point .
