Goblins' trait is that as long as there is one survivor, they can find ways to reproduce.
Thus, besides her daily training, the Hero's only combat activity is to challenge nearby serpent Magic Creatures with the Gleaming Scale Serpent, subduing them before searching for Goblins.

Nonetheless, the daily management was still left to the Gleaming Scale Serpent.
