The intensive phase has not yet been implemented, so Kerria is still an advantage
As far as I know ~ the damage of the purslane is not close to kerria (because the skill added on dmm is 4.3 times and the hula hoop is 2.8 times)...purslane wants to be the same as kerria, it must be supported by the team and must Injury bonus [crit damage] but I still hope she can do it.
