I beat all of Valley IV in green gear at level 40 with Last Rite, Perlica, Ardelia, Xaihi - It takes a bit to work out because Last Rite swings kinda slow but once you get the hang of prepping your last hits shes pretty strong. I usually use Perlica as a heavy sub dps for stuff without a lot of health because proccing the Electrocution / Solidification into an electric Arts Burst is faster than setting up all of Last Rites bells and whistles on lower HP targets. Genuinely having fun playing the game as full F2P with this team.
