Stamina problems: if you run into many monsters early on, such as in the Monastery, you need to conserve stamina. If confronted by a large number of enemies, or a few tough ones such as metallic slimes, run away so they have to go around a corner to get to you one by one if possible. My 3-party beat 15 seekers and later 4 metal slimes this way. There was no other way that worked because of stamina loss (and no one had stamina spell, but it would have been used up quickly anyway).
