The Zealot Grenade is a compact, cylindrical explosive device with an Art Deco-inspired design, featuring intricate geometric patterns engraved on its metallic surface. The body is primarily brass with a polished finish, accented with dark iron fittings and a glowing, blue-hued fuse mechanism that emits a faint steam-like vapor. The grenade's proportions are balanced, with a slightly tapered top leading to a wider base, ensuring a stable throw. Its surface shows minor wear and battle damage, hinting at previous use in the chaotic skies of Columbia.
