Trial of Lightning

The trial of lightning is the trial that must be completed in order to obtain the Thunder Beast Bow. It was created by the Diron to protect the item.

Location
In the Diron Kingdom, there is an old tree that was struck by lightning. This tree is a magical portal to the demiplane where the trial is located. When a creature enters the demiplane seals off so only a single creature may enter.

The Trial
Once in the demiplane the creature will find itself in a chamber with a podium about a meter across that has an indent shaped like an egg about the size of a fist in the center. There are 3 smaller perfectly round indentations spaced evenly around the pedestal. If the key is placed inside the pedestal, a door opens on the far side of the room.

The door leads to a round room with incredibly lifelike images painted on it. Each one depicts a lightning based creature (generally low CR). When a creature enters the room, the door vanishes behind them. When they touch one of the paintings that creatures comes out of the painting and attacks them, If they defeat the creature, a small round glass sphere that appears filled with lightning appears and the door reappears. When this stone is placed in one of the smaller holes, the door re-opens, the room appears exactly the same, except without the image of the creature that they faced. The second time through is the same as the first. After the second stone is placed in, the door opens a third time, this time there in only the image of a blue dragon. When touched, the creature appears and fights. When it is defeated, a third sphere appears.

When that is placed in the final slot, they create a circuit which causes the key to open revealing a smaller egg. The pedestal opens under the egg which shows that it is attached to a longbow where the sight would normally be. This is the Thunder Beast Bow. Once it is removed, the door leading out of the trial appears.
