i get past that point as my team is complete (that character should be the princess). i am using a boat to go from isle to isle. there is a new part of scenario each time i progress in the world. i will try to finish it (77 scenarios for an old mobile game is a score + 40 sub quest) but i am pretty sure i will miss main quest scenario (i already miss number 12 for example).
edit 13/10/19: i went really far in asdivine saga and i am really decided to finish it. so far there are multiple paths according to specific dialogue. i am at quest 40 for now. i only completed 2 missions but they are very simple. i will see if i can finish all the 38 remaining.
