  • The damage reduction is calculated after offensive Specials and skills that deal extra damage, such as Icon Class Red Sword.png Wo Dao+.
    • Damage reductions by percentage stack multiplicatively, unlike interactions related to the weapon-triangle, such as gem weapons and  Triangle Adept.
      • For example, if both Icon Class Green Axe.png Urvan and Deflect Magic 1.png Deflect Magic 1 activate, the total damage reduction is 86% instead of 110%, since the two skills reduce the damage to (1 − 80%) × (1 − 30%) = 14% of the original.
    • For more information, see Damage calculation.
  • Icon Skill Special.png Twin Blades and Icon Skill Special.png Deadeye will neutralize Blue Lion Rule's damage reduction effect when it triggers.
  • Icon Class Red Tome.png Þjálfi will reduce the damage reduction of Blue Lion Rule's damage reduction effect by 50%.
  • A foe with skills such as Null Follow Up 3.png Null Follow-Up 3 will disable Blue Lion Rule's guaranteed follow-up attack effect.
