Blaze's Fire Core is a pulsating, spherical artifact with a molten lava-like interior that glows intensely, encased in a cracked, obsidian-like shell. The core emits a warm, fiery glow, with dynamic, flame-like particles floating around it, suggesting immense heat and energy. The surface features intricate, glowing runes that pulse in sync with the core's energy, adding a mystical and powerful aura to the item.
