i just passed the trial with minutes to spare on maintenance . against all advice and guides on the forum after 4 tries , i decided screw it and try to beat rush her down to at least finish once . team wasrefia , level 55 6 cecil , charlotte , vaan , chizuru , elza friend . chizuru was DW and elza was DW with 485 ~ atk . ignored turn counters , ignored light resistance , i just emboldened with full break and shellga and went full DPS every turn . surprisingly RNG favored me and elza does enough damage with DW madness rush that i pushed past the HP barriers and was able to hold on using full life and a few elixirs . evoked diabolos and finished with elza ' s limit break . i only lost people to destiny twice . lucky me ! at least it ' s proof you dont need someone with massive whale attack stats to pass given some lucky RNG on the summon gauge .
