Start with the camp, then the encounter
Give yourself a reliable place to prepare before hunting for the first boss. A shelter, bed and workbench make a useful starting checklist. Gather your supplies, choose the equipment you want to use and leave room for a return trip rather than carrying everything you own.
Prepare the offering
Eikthyr is the Meadows encounter in this fieldbook. The summoning offering is two Deer Trophies. Keep the offering separate from your everyday gathering supplies so it is easy to check before you leave camp. Use the Meadows field notes to review the resources and creatures around your starting base.
Give the fight your full attention
Scout the area before you begin, check your supplies and think about the route back to your camp. Approach the encounter as a learning opportunity: observe the attacks, keep space to move and avoid turning a preparation trip into a rushed fight.
Turn the victory into your next plan
Hard Antlers lead to the Antler Pickaxe, opening the next material stage through copper and tin. Mark Eikthyr defeated on your roadmap, then review the Black Forest field notes and the Bronze Age workshop milestone. The reward matters most when you know what you want to build with it.
