The Hellforge Hammer is a massive, two-handed weapon with a menacing appearance, featuring a dark, forged metal head that glows ominously with ember-like cracks. The hammer's head is asymmetrical, with one side resembling a demonic face and the other a spiked anvil, symbolizing its origin in the fiery pits of Hell. The handle is wrapped in charred leather, providing a secure grip, and is adorned with infernal runes that pulse with a faint red glow. The entire weapon exudes heat distortion effects, suggesting its supernatural power.
