Tips for smoother sessions

  • Agree on a base location before everyone starts wandering.
  • Keep a shared list of needed materials to avoid overfarming the same thing.
  • Designate one navigator when diving into unfamiliar zones.
  • Decide who carries backup batteries, med items, and emergency materials.
