Lei tai

The lei tai is an elevated fighting platform where duels and tournaments are held. Duels fought on the lei tai may consist of fighting unarmed, with weapons, or using the bending arts.

Process
Anyone may issue a challenge to another person on the lei tai by climbing onto the platform. Parties must agree whether bending and weapons are allowed in a duel.

A duel only ends when the winner declares it to end. Even if one opponent is badly injured, the other may continue to attack for as long as they wish.

Fighters disrobe any heavy armor and fight in light clothing.

Known duels
A competition was held on a lei tai in a barn in the notorious daofei town of Hujiang. At the end of the unarmed fighting period, the champion was challenged by Rangi, who managed to defeat him without the use of her firebending. Her unexpected triumph secured the Flying Opera Company's respect with Mok.

After freeing Xu Ping An and him planning to restore the Yellow Necks to their former glory, Avatar Kyoshi challenged him to a duel on the lei tai, agreeing to the use of both weapons and bending. Xu shocked his opponent when he revealed his capacity for lightning generation and struck her with lightning. However, Xu was soon overpowered after Kyoshi entered the Avatar State and killed Xu.
