The Carthus Bloodring is a dark, ominous ring with a blood-red gem set in a twisted, skeletal band. The band appears to be made of aged, blackened metal with intricate carvings resembling bones and veins, giving it a macabre yet elegant appearance. The gem emits a faint crimson glow, suggesting a sinister power within, and the entire ring has a slightly weathered texture, hinting at its ancient origins.
