I'm trying to play a solo chanter, but I keep getting mobbed before I can get my powerful chants finished. For example I'm stuck with the xaurip quest (Clear out the Xaurips). I need 3 chants to get my Phantom summoned. By that time 4 xuarip are surronding me and I quickly die. Can anyone suggest any tips on how to start a battle with a solo chanter? Thanks
