The day before the Zagnei, fighters have to pure themselves. They do it by drinking a special preparation, called Dokai, which is made of the bark of a special tree, which is mixed with water. After taking it, warriors make themselves vomiting the drink. The water is supposed to bring with it many of the body’s impurities. After this ritual they don’t eat until the following morning. Warriors walk kilometers to come fighting at Zagnei, which takes place in a clearing. They stop when crossing a river in order to wash themselves, before decorating their bodies for the fight.
