31 ingame days for me, my opinion on attribute points is :points in magic are okay early until about cross(then i think its horrible), then I think maybe 2:1 for atk/def and once you unlock stone skin all def till you get near the 4500 cap.
got my 80 golds after 88 stages, the ones I skipped: 30,63,69,73,76,78,84,86.
Mostly being surrounded or disconnected from large pieces of land is very hard when the bots throw crazy amount of agro on you for being ahead or fighting back
