Tips for this line

  • If it evolves by level, nothing else is needed. Just battle and it happens.
  • If it needs a stone, those are mined as ore or crafted. Some have biome bias, so a stone you cannot find is usually in a biome you have not visited.
  • If it needs friendship, walking with it and levelling it up both build that. A Soothe Bell speeds it up and Luxury or Friend Balls start it higher.
  • If it needs a trade, a Link Cable simulates one so you do not need a partner.
  • An Everstone blocks evolution if you want to keep the current form.
