The Ninja Rage bug is a random bug in Final Fantasy VI involving the Ninja Rage that causes a formation error for Gau. Any party member that uses any scroll abilities (Flame Scroll, Water Scroll, and Lightning Scroll) (not the throwing items version), may or may not return to their original positions after use. The only way to achieve this without hacking is through the Ninja Rage, since it uses Water Scroll as an attack. This bug is not in reference to the actual scroll items that Shadow can Throw, but the enemy abilities that are used by Ninja and Covert.
