Ring of Summoning Affinity (Agathion)

Description

This ring is forged from electrum and inlaid with runes. If the wearer can cast summon monster spells, the wearer adds silvanshee to the 3rd-level list of monsters she can summon with those spells, adds vulpinal to the 5th-level list, adds avoral to the 7th-level list, and adds leonal to the 8th-level list. Also, once per day on command the wearer can use this ring to summon a silvanshee, as if by the summon monster III spell.
