Amulet of the Twelve Moons (Eberron)

A complete version of this potent artifact bears twelve precious or semiprecious stones - one corresponding to each of Eberron's moons. The origin of these enigmatic items of power remain steeped in debate. Many claim the first amulet was created during the War of the Mark as a means of uniting the fractured dragonmarked races. Shifter sages insist that Zev Jhaxos or one of his disciples received the first such amulet as a gift from the gods. Regardless of the amulets' true origin, none of the few known examples today bear all twelve stones. Each specific magic stone grants you a different magical power, and all stones act concurrently upon you when you wear the amulet. In addition to its gems' many gifts, the amulet of the twelve moons grants a +2 enhancement bonus on all attack and damage rolls made by unarmed strikes and natural weapons. With all twelve stones attached, this bonus increases to +5. The stones of power and the moons they represent are as follows.

• Zaranthyr: A white opal represents the midwinter moon indicative of powerful storms. This stone grants you immunity to effects of winds and precipitation of all kinds.
• Olarune: A clean white diamond symbolizes the late winter moon of Olarune. It grants a +4 enhancement bonus to your Wisdom score.
• Therendor: A turquoise stone corresponds to the early spring moon. You gain the ability to cast either cure serious wounds three times per day or mass cure light wounds once per day (CL 20th).
• Lyre: The mid-spring moon is represented by a malachite stone. It grants a +4 enhancement bonus on all Craft checks.
• Dravago: An aquamarine symbolizes the late spring moon. You gain a +5 bonus on Search and Survival checks. If you have druid or ranger levels, you gain a +5 bonus on your wild empathy checks as well.
• Nymm: A smoky rose quartz corresponds to the early summer moon. This stone prevents you from needing to eat or drink and you need only sleep 2 hours per day in order to gain the restful benefits of a normal 8 hours of sleep. You must wear the amulet a week before you gain the abilities of this stone.
• Lharvion: A golden yellow topaz represents the midsummer moon. It grants you a +4 insight bonus on Listen and Spot checks. You may cast see invisible three times per day (CL 20th).
