In Deltarune Chapter 4, you can find a boss that gives you a powerful weapon called Magic Axe after the fight.

Beating this boss will not only reward you with the Magic Axe (Justice Axe) for Susie but also a Shadow Crystal, which may unlock a different ending.

The fight is not hard if you know where to go and how to handle the battle.

How To Find The Secret Boss In Deltarune Chapter 4

To get the Magic Axe in Deltarune Chapter 4, you first need to find the boss. Start by backtracking to the climbable walls you saw earlier in the chapter.

Along the way, you’ll find a pool where you can throw Dark Dollars into a fountain. When you throw in the money, it causes the waterfall stream to split, allowing you to pass through.

A message will appear, saying, “A great donation will show your remembrance.” Once you pass, you need to solve the Golden Piano puzzle.

Completing the puzzle will trigger a doorway to appear behind the Old Man, who is the green lizard.

From there, go back down the bookshelves and move through the library until you reach the study room.

In this room, you’ll see the Magic Axe, and Susie will try to take it, but she won’t be able to grab it yet.

The Secret Boss Fight Strategy For Magic Axe In Deltarune

After a few strange interactions, Susie will be sent into the secret boss fight alone.

The green lizard old man will challenge her, and the Bell of Justice will ring, starting the battle.

He warns, “As long as you’re green, you can’t run away,” and says, “Unless you face danger head-on, their bullets will do you in!”

The battle has many levels and becomes tougher as it goes on. To win, you must avoid all of his attacks using your hammer. You’ll need to keep your HP high by dodging everything.

Some parts will challenge you to stop arrows from entering a square, while another section requires you to protect a heart inside a box from being hit.

These patterns repeat in different forms, and the key is to stay focused and consistent.
