Amulet of The Moon

If during nighttime 5PM - 4AM the wearer calls
for help to the Amulet it will provide a +3
Greater Cold Resistance: Studded Leather, Scale
mail, or Full Plate. It has no limit to how many
times it can summon the armor. Asking the
Amulet for help is a Free action. The armor is
dismissed after it's done being used.
It fits perfectly into the hand. It has a cool, pale
light emanating from it during the night.
