A ring of spell storing will contain 2-5 (d4+1) spells which the wearer can employ just as if he or she were a spell user of the level appropriate to use the spell in question. 

The class of spells contained within the ring is determined in the same fashion as the spells on scrolls.

The level of each spell is determined as follows:

• cleric: d6, if 6 is rolled, roll d4 instead

• druid: as cleric

• magic-user: d8, if 8 is rolled roll d6 instead

• illusionist: as cleric

Which spell type of any given level is contained by the ring is also randomly determined. 

The ring has the empathic ability to impart to the wearer the names of its spells. 

Once class, level, and type are determined, the properties of the ring are fixed and unchangeable. 

Once a spell is cast from the ring, it can only be restored by a character of appropriate class and level of experience, i.e. a 12th level magic-user is needed to restore a 6th level magic-user spell to the ring. 

Spells stored require 5 segments each to cast.
