The Master's Scroll Bug is a bug in Final Fantasy VI that involves the Master's Scroll Relic (known as the Offering in the SNES version). When equipped, the Master's Scroll allows the character to attack four random targets at half damage each time when using the Attack command; however, certain weapons have special damage algorithms that ignore this penalty:

• The Dice and Fixed Dice ignore the penalty, due to being based solely on the user's level and randomly-generated numbers.
• The Ultima Weapon also ignores this penalty, as its power is based on the user's current HP compared to their max HP, as well as their level.
• The Valiant Knife does not ignore the half damage penalty; however, the special effect of the weapon, which deals damage equal to the user's current HP subtracted from their max HP, is unaffected due to it being added in after the damage penalty.
