the grind is to be expected for it is a rpg. the advice i can give is at the end of day 1 and 2 use the time after to grind some and rest at the lurvak i think its name is. if the is two enemies tend to use the skills that hit both like hot sauna or cold shower and single enemies i use singeing strike. also on the activity's i pick the ones for gaining hp , mp and more attack. im only on the second domain tho.
