Hello, well i don't want to be bored: for this the bg is not necessary
1. Kill mobs in the area. no matter if someone die.2. is easier if someone in the group shooting stops the boss from this place .
3. the other group members can kill the boss mobs without interfering
4. when all the mobs are eliminated whole group should be directed toward this position
5.when the boss reaches the position shown, then start the attack
6. damage typically is 500 -700 , doc needs to be fast.
7.but when the boss prepares his main attack, its tail glows black at that time all must hide behind the yellow car. boss's attack fails 100% secure
8. to repeat the strategy in all sides of the yellow car.
