Dread Core

Dread Cores are enemies summoned by The Flaming Pumpkin boss. In the first phase, they will sit stationary and not do anything until they are killed and must be defeated to progress the boss fight. In the second phase, the flames act the same, except for the fact that they despawn after 5 seconds and are not needed to be killed to progress the fight. They will also both inflict the On Fire! debuff if they hit a player.
