Notes

  • Equipping this mod will set weapon's Multishot to its default ignoring other bonuses, even negative effects (e.g.  Rifle Riven Mod).
  • The Weak Point Damage is multiplicative with bonuses to Headshot Multiplier, such as from  Primary Deadhead.
  • The Weak Point Damage is additive with the Weak Point Multiplier on enemies.
    • The values described on the mod are misleading, the actual damage bonus being 1.5x of the listed value.
      • For example, a typical humanoid enemy such as a Butcher has a 3x Weak Point Multiplier on its head. A rank 10 Acuity will increase this value to 3 + (3.5 * 1.5) = 8.25x
        • This is a relative damage increase of +175%
      • MOA's backpack is one exception to this, accurately adding the listed damage bonus to its Weak Point Multiplier.
    • Note that damage increase may vary between different types of enemies, since not all enemies will receive "Headcrit" damage, for example MOA and Lumbering Fragment.
    • Weapons with Area of Effect damage or other special projectiles that inherently do not deal increased weakpoint damage will not gain increased damage from this mod.
  • Weakspots created by  Banshee's  Sonar do not count as weak points.
