Create a powerful greatsword inspired by ancient divine relics, fitting within the dark and mystical world of Elden Ring. The blade should be massive, with engravings of serpents intertwined along its length, symbolizing both destruction and rebirth. The hilt should have a tarnished silver guard and be wrapped in black dragon hide. The weapon channels both frost and arcane magic, allowing for chilling strikes and ethereal blasts. Ultra detailed, best 8k texture, perfect mesh.
