The rhythmic clanging of hydraulic presses echoes, the venting of steam pierces your ears, and the watchful eye of the core gazes into your soul.

— Bestiary (The Soulstone Core)

The Soulstone Core is a Hardmode boss intended to be fought right before Plantera. While it is active, the vanilla track Storm will play.

Spawning

The Soulstone Core is summoned by interacting with the Onslaught Terminal within The Factory's Core Room.

Behavior

The Soulstone Core stays still in one spot with the camera focusing on it, if the camera is smaller than the room, it is lowered to where the floor is visible. Dealing over 400 damage causes the core to open. After opening, the core will close after 16.67 seconds.

Attacks

• Turrets: 2 Plasma Turrets will spawn on either side of the room and will fire Plasma Lasers in 3 shot bursts. These turrets cannot be destroyed while The Soulstone Core is present.

Closed

While closed, the following attacks can occur. The Soulstone Core will not deal contact damage while the core is closed.

• Drones: Summon Infernal Arson-al/Plasma DronePlasma Drones that fly to a set distance from the player and fire Plasma Lasers.
• Explosive Drone: Summon 3 / 5 / 7 Infernal Arson-al/Explosive DroneExplosive Drone that fly at the player and explode on collision.

Open

While open, the following attacks can occur. Turrets will not fire while the core is open.

• Laser Defense: The Soulstone Core fires a rotating circle of 3 Plasma Lasers.
• Factory Support: Infernal Arson-al/Factory WorkersFactory Workers will move into the room and fire Plasma Lasers at the player.
• Heat wave: The Soulstone Core spreads 2 rotating streams of fire, opposite to each other.

Aftermath

When its life reaches 0, it drops its loot and begins to explode, Factory Workers and drones will retreat and despawn when offscreen, and turrets will deactivate. Any players still in The Factory after 20 / 18 / 16 seconds instantly die to the explosion. After all this, The Factory will be inaccessible for 1 hour.
