How to Defeat The Jackenstein Boss?

Jackenstein is one of the most challenging bosses in Deltarune. His attack patterns can catch novice players off guard, but if you master the method, you will be able to defeat him successfully.

Avoid the Battle

When the battle begins, you will be in a dark maze. Do not attack actively, but focus on collecting the scattered glowing TP energy balls. Evade the periodically appearing pumpkin stalkers and locate the secret key to access the maze's exit and advance to the next level.

Focus on Defense

After successfully escaping the maze, the battle officially enters the turn-based mode. In each round, give priority to the "defense" command instead of attack. Defensive maneuvers offer protection while significantly enhancing TP recovery.The energy balls that are not collected in the maze will also be automatically converted to TP. Make sure that TP reaches at least 60% to launch an effective attack.

Release Energy

When TP reaches 60%, the "Release" option will appear in the "Action" menu. After selecting it, you will return to the maze, but this time your identity will be transformed into a hunter. Chase and hit Jackstein, and each successful hit will reduce his health. After attacking once, the battle will reset to turn-based mode, repeating the cycle of defense-energy-counterattack until he is defeated.
