The Core is the boss located inside the Factory and serves as the objective of the Factory Raid event. Players must destroy it before the event timer expires to successfully complete the raid and earn the available rewards.

Unlike regular enemies, The Core does not move or attack, making the fight entirely focused on dealing as much damage as possible within the time limit. Because of this, high damage output is far more important than mobility or defensive abilities, and players often work together to destroy it before the Factory closes.

Spawning:
The Core appears every 1 hour and 30 minutes during the Factory Raid event. Once the raid begins, players have 5 minutes to destroy it before the event ends. Since the boss remains stationary, success depends entirely on dealing enough damage before time runs out.

Once the 5 minute timer expires, the Factory doors close and the Factory Raid ends if The Core has not been destroyed. Players who are still inside are teleported out of the Factory, and no rewards are given for the failed raid. They must then wait for the next Factory Raid for another chance to destroy The Core.

Drops:
Destroying The Core rewards all participating players with $65,000 to $85,000 and 600,000 to 750,000 EXP. However, the player who deals the highest total damage receives an additional reward of one random Blox Fruit, making the event highly competitive even when completed with a group.

In addition to its standard rewards, The Core can also drop Acidum Rifle and Radioactive Material. These items are not guaranteed, giving players another reason to participate in the Factory Raid, especially if they are farming for equipment or crafting materials.
