Charm necklace
Charms of this sort occupy the throat body slot, but can be worn simultaneously with up to five other charms, which all function normally. (More than one sort of charm can’t be worn at once, however.)
A charm necklace is typically made with attachment points for six charms. The necklace itself is nonmagical (though it may have innate value as a piece of jewelry).
You must wear a charm for 24 hours before you can access its abilities. If it is taken off, it becomes inactive until worn for an additional 24 hours.
Charm of the uncaring archmage
This charm is a bloodstone eye in a pentagonal setting. It slows the wearer’s perception of time, allowing him to cast a single spell more quickly. When it is activated (a swift action), the next spell of 3rd level or lower that the wearer casts that has a casting time of 1 full round can be cast as a standard action instead. If the wearer doesn’t cast such a spell by the end of his turn, the effect fades.
