The Antitoxin is a sleek, cylindrical vial with a metallic base and a glass body, showcasing a vibrant green liquid inside. The vial features intricate Orokin engravings along its metallic parts, glowing faintly with a bioluminescent blue hue. The cap is designed with a secure locking mechanism, indicating its precious contents, and the glass is slightly frosted to diffuse the liquid's glow, giving it a mystical appearance.
