Amber acorns of the Moonwood Circle

Amber acorns was the name for a type of necklace made by the druids of the Moonwood circle of the forest of the same name.

Description
The necklace appeared as four acorns carved from amber, strung together with a cord that resembled interwoven roots. Each acorn contained a small piece of elemental matter, one for each element of air, earth, fire and water.

History
Prior to their disappearance in 1305 DR, following a series of conflicts with the People of the Black Blood known as the Beast Wars, the druids of the Moonwood had setup a series of caches of magical items across what was then called the Silver Marches. The most well-known of these items were the amber acorn necklaces.

Powers
Once per day, the wearer of this necklace could cast Summon nature's ally VI and conjure forth a creature attuned to each elemental type. Each elementally-attuned acorn had one daily charge, allowing for four creatures to be summoned.
