Undertale’s Pacifist Route is all about kindness, mercy, and understanding—until you meet Asgore. The king of monsters forces you into a fight, destroying your MERCY option and leaving you no choice but to battle him. But even in combat, you can stay true to your pacifist ideals. Here’s how to beat Asgore without compromising your run.
Asgore Dreemurr isn’t just another boss. He’s a tragic figure, a grieving father forced into a terrible role. When you face him, he removes your ability to spare him outright, making the fight feel brutal. But don’t worry—your Pacifist Route isn’t ruined. You’ll still get the chance to show mercy later.
Before the Fight: Preparation Matters
Success starts before the battle. Here’s what you need to do:
- Grab the Right Gear
- In New Home, you’ll find the Worn Dagger and Heart Locket in gift boxes. These are your best options for this fight. The dagger gives solid attack power, while the locket boosts your defense.
- If you prefer healing over damage, the Burnt Pan increases the effectiveness of healing items, which can be a lifesaver.
- Stock Up on Healing Items
- Load up on Butterscotch Pie (if you still have it from Toriel), Cinnamon Bunnies, or Legendary Heroes. These items heal well and, in the pie’s case, can weaken Asgore emotionally.
- The Temmie Armor is an expensive but overpowered option if you’ve struggled too much. It regenerates health and reduces damage significantly.
- Save Before the Fight
- Use the save point right before Asgore’s throne room. If things go wrong, you won’t have to backtrack.
The Battle: Lowering His Defenses
When the fight starts, Asgore immediately destroys your MERCY button. You must fight him, but you can still minimize violence.
Step 1: Talk to Him Three Times
- Open the ACT menu and select Talk. Do this three times.
- Each talk weakens him—his attack and defense drop, making the fight easier. This only works if you haven’t killed any monsters.
Step 2: Use the Butterscotch Pie (If You Have It)
- Eating the pie reminds Asgore of Toriel, making him hesitate. This further lowers his stats and heals you.
Step 3: Fight Strategically
- Attack with the Worn Dagger for the best damage. Time your strikes so the bar lands in the middle for maximum effect.
- If you’re using the Burnt Pan, focus on healing when necessary—its damage is lower, but the extra HP from items helps.
Dodging His Attacks
Asgore’s moves are similar to Toriel’s but faster and deadlier. Here’s how to survive:
- Fire Waves – These come in spirals or waves. Stay near the center and move in small circles to avoid them.
- Hand Flames – His hands will swipe across the screen, leaving fireballs. Lead them to the edges so they don’t trap you.
- Color-Based Attacks – His eyes flash blue or orange before he swings his trident. Blue means stand still, orange means move.
- Ring of Fire – Flames close in from all sides. Find the small gap and escape without panicking.
The Final Phase: Showing Mercy
After dealing enough damage, Asgore kneels, and the MERCY option returns.
- Spare him. Even after fighting, you can still choose compassion.
- He’ll give a heartbreaking speech about his regrets and lost family.
- Then, Flowey interrupts, stealing the moment and leading into the next boss fight.
Extra Tips for Success
- Stay Calm Under Pressure – His attacks speed up as his health drops. Focus on patterns rather than frantic movement.
- Heal Wisely – Don’t wait until you’re at 1 HP. If you’re below half health, use an item.
- Practice Makes Perfect – If you keep dying, take a break. Muscle memory helps in bullet-hell fights.
Why This Fight Matters
Beating Asgore in a Pacifist Run isn’t just about skill—it’s about persistence and empathy. The game forces you to fight, but the real victory comes when you spare him anyway. It’s a powerful moment that reinforces Undertale’s themes of forgiveness and second chances.
Now that you know the strategy, go forward with determination. Good luck, and may your heart stay full of mercy.
