The Jar is a magical portal to the elemental plane of electricity and light. Each evening, when exposed to the rays of the setting sun, the Jar opens a gateway and calls forth a mindless elemental placing the creature in under the control of the Jar's owner. Each summoned elemental is stored within the Jar, which can hold up to three such creatures, until the lid is removed, releasing the creatures to do the owner's bidding. Once released from the Jar the elementals remain under the owner's control for eight hours, before returning to their own plane of existence. The elementals appear as small globes of pure yellow light, and have the following characteristics:
- Great flight ability. The elementals are swift and agile fliers, able to stop and turn instantly.
- Shocking Bolt - The elementals can inflict a jolting energy attack upon anyone within ten feet, inflicting average damage.
- Illumination - The creatures can brighten or dim their form, creating a light as dim as a match or as bright as a good lantern.
- Hypnotic Dance - The elementals can move in a hypnotic pattern which is capable of beguiling anyone looking at it (Good test of will to avoid being ensnared). Those affected mindlessly follow the elemental, enchanted by the desire to capture and hold the glimmering lights.
