  • Serration damage is applied before any other damage type. Therefore, every other damage increasing mod benefits from Serration. E.g. a weapon with a base damage of 18 equipped with a rank 9 Serration mod (150%) would have a new base damage of 45: 18 + (18 × 150%) = 45
    • This new base damage will be what is used to calculate elemental damages.
  • When paired with other mods:
    • Multiplicatively stacks with Faction Damage Mods for a maximum of +244.5% damage.
      • +310.75% for Primed Faction Damage Mods
    • Additively stacks with Heavy Caliber for a maximum of +330% damage.
    • Stacks with Heavy Caliber and Faction Damage Mods for a total of +459% damage at max rank.
      • +566.5% for Primed Faction Damage Mods
  • At higher ranks the fusion cost of this mod becomes quite costly. Upgrading other mods simultaneously makes for a better investment of your Endo compared to only enhancing this one alone.
    • It is suggested to upgrade this mod to at least rank 5 quickly though, since it is useful on a lot of weapons.
    • Maxing this mod requires 20,460 Endo and 988,218 Credits.
  • Due to how it affects the base damage, this mod is necessary for all primary weapons in order to use them optimally. Few mods can replace the effectiveness of this mod.
