Today, I will introduce the hidden bosses in Deltarune. Hidden bosses often have unique attack patterns and combat mechanisms, which are significantly different from regular battles. Their appearance not only tests the player's operational skills but also challenges the player's depth of understanding of the game system. Successfully unlocking and defeating these hidden bosses can not only bring generous game rewards but also help players progress more smoothly in subsequent adventures. Let's take a look together.

The hidden boss in Chapter 1 is Jevil, the Mad Jester. The unlocking process is full of exploration and puzzle-solving elements. Players first need to reach the save point on the first floor of the castle, then head to a specific floor. In the prison, talk to the relevant character, follow the instructions to find the old cat shopkeeper for a conversation, and thus obtain the first key fragment. Retrace your steps back to the forest area, which is lush and green. In an open space, four dancers are gracefully dancing around an ancient chest. Carefully observe the dancers' positions, and you will find a hidden path leading downward beneath their feet. Enter through the gap formed by the dancers, follow this hidden path down, and you will find the second key fragment. Finally, return to the specific floor of the castle, use the repaired key to open the prison, and Jevil, the Mad Jester, will appear.

The unlocking process for the hidden boss in Chapter 3 is also quite complex and divided into multiple stages. In the first round of preparation and mini-games, players need to obtain entry qualifications. This can be achieved by efficiently or flawlessly completing battles and tasks in major rooms, earning an S rank to proceed. If it's difficult to get an S rank, players can go to a specific NPC and spend points to unlock directly. After achieving an S rank, the S-rank exclusive room will open. Inside the room, find and start the arcade machine, enter the mini-game, and upgrade your weapon. Exploring towards the upper left, you will find a treasure chest containing the key item, the ice key, needed to unlock the hidden boss.

In the second round of the process, players need to trigger the ghost event. After obtaining the boat, continue moving to the upper left until you see a door below. Start the door and enter a new mini-game. This round has a different gameplay from the first, requiring players to judge the direction based on the ghost's hints. When the ghost follows your movement, it indicates the correct direction; otherwise, adjustments are needed. After correctly completing the route selection, the red door will open. Enter to trigger a key plot, upgrade your weapon, and use the new weapon to cut through the fence and enter the hidden area. Clear the room to trigger the battle with the hidden boss.

The introduction to the hidden bosses in Deltarune is complete. By analyzing the unlocking process and combat strategies for the hidden bosses in Deltarune, players should have a clearer understanding of how to challenge these powerful opponents. Each step requires players to invest time and effort in research, opening up more adventures in the world of Deltarune.
