It depends on if you decide to solo, and on what difficulty. Also, nobody has any idea of the actual damage range of the bosses yet, including if there is any special effect. The DMM japanese wiki is not really informative either courtesy of bad google translation. So nobody can answer that concretely till tomorrow.
