UNDERTALE: How to Defeat or Spare Muffet

Basic Information about Muffet

Monsters in Hotland

Muffet is a monster that appears in Hotland. Regardless of the route, you will encounter her in the Spider's Den. If you are aiming for the Pacifist route, you should spare her. On the other hand, if you are aiming for the Genocide route, you must defeat her.

Tips for Beating Muffet Boss Battle

Check the Next Attack

Muffet will tell you the type of attack she will perform before attacking. Get a grasp of the characteristics of the items she uses for her attacks and prepare for the next attack accordingly.

Pay Money to Decrease Muffet's Attack Power

Paying money to Muffet will decrease her attack power for the turn. However, the price will increase for subsequent payments. If you have enough money, consider paying before facing her difficult attacks to reduce the damage.

Lower the Price to 5G Once by Struggling

By choosing the "Struggle" action, you can lower the price to 5G once. However, this will cause the price to significantly increase to 35G on the next turn. It's recommended to save struggling for the later part of the battle.

Control the Soul Near the Center of the Screen to Avoid Attacks

Muffet will attack using spiders, donuts, and croissants. The donuts move up and down, but all attacks move along a certain line. Therefore, control the soul near the center of the screen and move it up and down to avoid the attacks.

The Pet Moves Left and Right while Aiming for the Top of the Screen

When the sign for "Cupcake" appears before the next attack, the pet will crawl up from below after the spider's attack.

Getting hit by the pet will cause damage, so move left and right while navigating through the gaps between the spiders and constantly try to escape upwards.

How to Spare Muffet

Use Spider Sweets

To spare Muffet, use the item "Spider Donut" or "Spider Cider" as soon as the battle begins. On the next turn after using the Spider Sweets, a message saying "She seems satisfied" will appear, allowing you to spare her.

Spider Sweets Can Be Purchased Cheaply in the Ruins

The Spider Donut and Spider Cider can be purchased cheaply at the Spider Bake Sale in the Ruins. To purchase them in Hotland, you will need 9999G and a significant amount of money. It is necessary to buy them in advance in the Ruins.

Pass 17 Turns Without Attacking

If you want to spare Muffet without having the Spider Sweets, let 17 turns pass without attacking her. At the end of the 17th turn, the misunderstanding will be resolved with the message "You supported the spiders in the Ruins," allowing you to spare her.
