Shadow is a mysterious ninja with the 'Throw' command, allowing him to hurl weapons and items for massive damage. He is incredibly fast and excels at single-target damage. Equip him with the fastest daggers or katanas. His dog, Interceptor, occasionally blocks attacks or counter-attacks. Espers that boost Speed or Strength are beneficial. The 'Thief Knife' can give him 'Mug' for utility. His 'Throw' ability can be expensive, so use it strategically, especially with Shurikens and Scrolls.
