This fight will pit you against two waves of Ixali, the first being two scout wolves and an Ixali Sabreur, with a Fogcaller and Swiftbeak joining soon after. The Sabreur is the main boss, while everything else are weak adds that are easily killed.
Put up your damage buffs including straight shot, and apply Venomous Bite and Windbite to the Sabreur, then take out the wolves. For the second wave, focus on the Fogcaller, as it can heal, then on the Swiftbeak. All the while, try to keep your DoTs on the Sabreur. Once the adds are all dead, finish off the Sabreur.
