The Smelter Demon stands nearly three meters tall, a hulking mass of blackened, scorched iron, his armor fused to his flesh and broken by jagged molten seams. His core burns constantly—a furnace embedded in his chest, glowing with a haunting, inner rage. The only sound that escapes him is the hiss of metal shifting and the low groans of lava coursing through ancient joints. His arms are inhumanly long and his clawed gauntlets move with deadly precision. He has no face, only the skeletal remnants of a helm twisted around an empty crown, symbolizing a forgotten knighthood lost in flame.

The Smelter Demon stands motionless, the glow in his chest pulsing slowly like a dying star. A soft hiss of steam escapes from his back as he shifts slightly—watching the cursed undead within it's husk horned helmet.

The Smelter Demon began to fight with overwhelming brute force. His massive sword cleaves through walls, armor, and shields alike. He relies on strength, furnace bursts, and timed explosions of inner flame. Occasionally, he will ignite his entire body, entering a “burning phase” where his proximity causes searing heat damage and his attacks become faster, more erratic, and viciously heated.
