Parameter Reduction (commonly referred to as Stat Reduction or Stat Down) is a debuff that decreases a certain stat(s) of the designated target. Similar to how stat calculations work, parameter reductions are subtractive with each other along with stat boosts.

This debuff can stack additively with Parameter Reduction Added to Attack.

Status Cleanse can cleanse all Parameter Reduction debuffs.

Status Negation cannot negate Parameter Reduction debuffs.


  • A unit with a 180% Atk buff and a 50% Atk Down debuff will result in a 130% boost to Atk.
  • A unit with a 180% Atk buff, a 50% Atk Down debuff, and a 30% Atk Down debuff from added Atk reduction to attack, will result in a 100% boost to Atk.
