There is now a use for Travellers! Keep atleast one traveller character, for they are the participants in the Traveller Event! This event is a wild fight inside a ring, with 5 travellers at a time. The survivors of the ring will proceed to the next round, until the last ring has its last amount of players. The winning traveller will be rewarded an item.
TIP: Gather items on your main character, and transfer the good ones you don't need to your traveller character, so he can become stronger for the event.
