Undyne the Undying is one of the most difficult bosses in the game, and defeating her can be a challenge. Here are some tips to help you beat her.

  1. Equip a strong weapon. Undyne is a powerful opponent, and you’ll need a weapon that can take her down quickly. A sword or an axe will work well, as will a ranged weapon if you’re short on time.
  2. Stay calm and focused. Undyne is very fast and can easily dodge your attacks if you’re not careful. Keep your cool and stay focused on what you’re doing, and you’ll be able to take her down easily.
  3. Use your environment to your advantage. Undyne’s attacks are based around water, so use that to your advantage by attacking her from below or from behind where she can’t reach you easily.
  4. Use items wisely. Many of the items in the game can help you defeat Undyne, so use them wisely if they come into play during the fight. For example, using a bomb to destroy an obstacle or using a healing item when needed will help you stay alive longer and defeat Undyne more easily ..
