The Flaming Pumpkin can be summoned manually using a Dread Lantern at Night. When the boss spawns, the face of the boss will appear first. It will stay a couple of seconds before the pumpkin itself spawns.
In the first phase, the boss will stay stationary at the place it spawns, while at the same time being affected by gravity. All the Dread Cores that are currently alive must be defeated to damage it.
When the boss spawns, it will summon 4 Dread Cores around itself, connected with a vine
At 75% HP, the pumpkin will spawn 6 cores. This repeats at 50% HP and 25% HP, adding 2 more cores each time.
The pumpkin will also fire burning seeds and bouncing fireballs at the player, both inflicting the On Fire!Debuff. The fire rate of these projectiles will speed up gradually as the pumpkin's health decreases.
The pumpkin will now jump to follow the player. When it hits the ground after a jump, it will spawn a row of 10 spikes to its left and right.
The pumpkin will alternate between firing 8 burning seeds and 5 bouncing fireballs at the player
The pumpkin will also fire a barrage of pumpkin flame seeds into the air.
