The ring of visibility is a special ring that can be obtained from Rasolo the merchant, after the player retrieves his gilded cross for him during the quest Desert Treasure. Wearing the ring lets the player see certain mysterious ghosts and items that are normally invisible. The ring of visibility cannot be made using the Crafting skill.
Whenever the player dies while wearing/having the ring of visibility in your inventory, the player will lose it even if he/she had less than 3 items on him. There is an exception to this rule, however, if the player dies while fighting Damis during Desert Treasure. If lost, the ring can be reclaimed from Rasolo.
