The Spartan Rage Stone is a medium-sized, roughly hewn stone imbued with the essence of Kratos' fury, featuring a deep crimson core that pulsates with a faint glow. Its surface is textured with ancient Norse runes carved into the dark, volcanic rock, surrounded by metallic bands of weathered bronze that reinforce its structure. The stone's irregular, angular shape suggests it was broken from a larger monolith, with sharp edges that contrast against the smooth, polished runes.
