After clearing all the monsters that were in his way, Jiang Fei rushed to the boss and immediately attacked it.
Sulu was chained to the ground in the hall and was unable to move around. The most used skill was the black lightning bolt that dealt 40,000 to 50,000 damage to Jiang Fei. A powerful damage but nothing to be worried about.
The only problem with this boss was the Draconian Guards that were summoned. These guards were strong and were spawned right behind the party. Thankfully, the tanks of the party had nothing to do since none of them could approach the boss. Hence, when the monsters spawned, the tanks immediately drew their attention and the DPS attacked them.
