Description
This ring is made of intricately marked brass. If the wearer can cast summon monster spells, the wearer adds tripurasura to the 3rd-level list of monsters he can summon with those spells, adds adhukait to the 6th-level list, adds upasunda to the 7th-level list, and adds aghasura to the 8th-level list. Also, once per day on command the wearer can use this ring to summon a tripurasura, as if by the summon monster III spell.
