Smoke bombs were a rather low-grade item in the game, and it could be sold in many places. It was rather loved by players during the beginning of the game, and it was usually used to attack other players or for fleeing purposes. It was a cheap item with tangible benefits.
Smoke bombs were not offensive weapons and could only create smoke in a small area, but it could be used to obstruct sight. Hence, when the Class One Hall members faced the sudden invasion by countless smoke bombs, they found themselves rather resigned as well. They could only watch helplessly as balls of smoke quickly spread out in the lawless street and blur their vision, and they could do nothing about it.
While the smoke bombs came from the street, this sort of action was something that the multiple elites who maintained the order in Dragon's Gate could tolerate.
