Aion Guide Coliseum
A Coliseum is located in the downtown of every main city of both Asmodian and Elyos. It is a very large round area in the form of the Colosseum. A conversation with the NPC may lead you into the Coliseum.
This is the place for open battle. Members of the same race could fight against each other to test their skills and strategies. Training is encouraged and there would be no experience even if you are fought to death.
You can enter the Coliseum by yourself or with a group of teammates. If you are not by yourself, you will not be able to strike your allies. You can instantly distinguish your enemies from your allies for the names of the enemies are red. This makes the organization of massive battles fairly easy. Once you are dead, you would be teleported automatically out of the Coliseum and placed behind the NPC at the entrance. You can take a break there to restore your health and mana, or enter again right away.
You are allowed to use the Coliseum for countless times and if you choose to go there in a Legion, you could learn PvP skills and enhance the strength of your class.
