Today, I'm bringing you the content on how to defeat the hidden boss in Chapter 1 of Deltarune. In the game structure of Chapter 1 of Deltarune, the existence of the hidden boss, Jevil the Mad Jester, greatly enriches the exploration dimensions and depth of combat challenges in the game. The unlocking process is closely intertwined with the game's scenes and plot, from the mysterious floor reached by the castle elevator to the discovery of hidden clues in areas like the forest and plains. Each step tests the player's control over game details and their exploration skills. Let's take a closer look together.

To unlock the challenge of Jevil, first, advance the main storyline to the castle area. After reaching the save point on the first floor of the castle, take the elevator to the mysterious floor marked “?????”. In the cell, talking to the NPC can trigger the task of collecting key fragments. The first key fragment can be obtained in the town, by finding the old cat shopkeeper and choosing the highlighted conversation option related to "the strange prisoner" or "the being in the cell". The old cat shopkeeper will then directly hand it over to the player. The second key fragment is hidden in the forest area. Upon returning to the forest, pay attention to the spot directly below where the four NPCs are dancing; there is a hidden passage. Enter this dark path and go to the end, where a chest contains the second fragment.

The third fragment requires solving the puzzle box in the plains area. From bottom to top, the sequence is "Diamond, Heart, Club, Spade". After entering the correct combination, the mechanism will open, and you can obtain the fragment. After collecting all three fragments, go above the Hotdog Stand save point to find the blacksmith, and give him the fragments to repair them into a complete key. During this time, you can also choose to have the blacksmith fix the cake that was destroyed by Susie. The repaired top-notch cake might come in handy during the subsequent battle. Finally, return to the “?????” floor, use the repaired key to open the cell, and the battle with Jevil will officially begin.

To face this high-intensity battle, thorough preparation is essential. The roles of the team members need to be clearly defined. Kris serves as the main damage dealer, and equipping a high-attack weapon like the Steel Sword can effectively increase damage output. Ralsei takes on the role of support and healing, with the group healing skill Prayer being crucial for maintaining the team's HP. Susie focuses on disruption and control, using Taunt to draw the boss's fire, creating a stable environment for teammates to deal damage. It's indispensable to carry recovery items, such as the top-notch cake which increases the entire team's HP by 90, and the Dark Candy which restores 60 HP to a single character. These items can timely replenish the characters' HP during the battle, ensuring the team's survival.
