Personal items

For every two lives lived, or for every thousand victories in personal quests, or for one life and five hundred victories, you can buy an ownership coupon from a quester. It gives you the right to make any unlimited item your personal property. Only the owner may take such an item in hand.

To make an item personal, take the coupon and the item in your inventory, then type: use coupon object

Personal chests also exist -- you can tell them apart by the (Personal) aura -- and even personal mansions.
