Ring of sustenance

The ring of sustenance is a useful magical ring that provides the benefit of providing nourishment and restful effects while worn. While under the effects of this ring, the PC does not require food or drink, and requires much less in the way of actual sleep. For the ring to work properly, it must attune itself to its user. This process involves wearing the ring for a full week (7 days), while performing normal actions. Removing the ring at any time starts the process over. After the week has gone by, the ring functions normally. While wearing this ring, a PC may elect to sleep only 2 hours, and gain the benefit of a full 8 hour rest. Wizard spells are not studied any faster with this benefit, however, and still require the normal study time.
