Prosperian attractor

A Prosperian attractor is a magical chest-shaped artefact carved from ebony. By force of magnetism it hungrily snaps up any coins that might fall from the denizens, monsters, or miscellaneous creatures that its owner might slay, depositing the gold into their inventory. The bounty may then be safely packed away by the owner without fear from thieves, friendly gold-grabbers, penny-pinching panhandlers, or kill-stealers.
