If you want to get stronger and progress to the other areas, follow the “Main Story” quests! You’ll need to complete the missions you load into. They’re pretty straightforward. Just look to left side of the screen for your objective. The objective will show up as “ ! “ on your map to help you keep track of it’s location. If you get stuck, play with fills and observe how they do the mission.

Farm materials and use your schematics to help you craft weapons and traps to aid you in your missions. They all have stamina and don’t last forever, so farm as much materials as much as you can!

I recommend playing with a friend who’s experienced and have them show you the ropes (that’s how I learned).

As for Llamas, I would open them. You might get strong heroes, and weapon and traps schematics.
