Classic Diablo pixel art style

Sinister dark fantasy feel with oppressive atmosphere. Angular, heavy, exaggerated proportions with sharp edges. Palette dominated by obsidian, ash gray, deep charcoal, and dried blood, punctuated by intense infernal hellfire glows of fiery amber and bright crimson gem highlights. Stark high-contrast shading with pitch-black shadows and harsh fiery rim light. Gritty, weathered surfaces with rust, dried blood, and chipped stone texture.
