Isabella sent out an Abyssal Flame, and Jiang Fei literally ran after the flying missile. When the ball of black flame smashed into the boss, Jiang Fei leaped past the explosion and gave it a good rap on the head.
A Level 35 Advanced Elite was nothing to Jiang Fei. Even though magical attacks were highly effective against armored players, Jiang Fei could take the hit. He had equipment that could negate damage taken by 20%, as well as an additional magic defense that could further lower magical attack. In the end, Jiang Fei took what that was slightly a hair over a thousand damage.
The Foot Soldiers' attacks were heavy but slow. Unlike bosses, these lower ranked monsters were susceptible to Stun and Freeze effects. With potions, Jiang Fei could stay right on top of the Bloodborne Foot Soldier for a good period of time.
