Magnum Force is a mod that increases damage of secondary weapons at the cost of increased spread (reducing accuracy) by +15% and +0.5 per rank, at a maximum of +165% and +5.5 at rank 10, respectively. Some weapons will have additional spread added, in addition to the base amount.

Notes[]

  • Instead of reducing the accuracy by 5% per rank, each rank increases spread by a specific value per rank depending on the weapon. This effectively reduces accuracy but may reduce it by greater than 5% per rank (according to the Arsenal UI).
  • This will increase the spread of pistol shotguns.
  • Damage increase value of this mod stacks additively with that of Mod TT 20px Hornet Strike and Mod TT 20px Augur Pact to a total of +475% base damage.
  • Accuracy reduction varies by weapon, even for those with 100 accuracy. For example, Acrid Acrid (which has 100 accuracy, decreased to 1.6 at max rank) needles fly very far outside of the reticle, while Akstiletto Akstiletto (which has 23.5 accuracy, decreased to 10.3 at max rank) spreads bullets considerably but do not stray too far from the reticle.
  • The final accuracy after installing Magnum Force can be found by the following formula:

Tips[]

  • Mod TT 20px Targeting Subsystem can help negate the accuracy penalty from this mod once its effects activate when combined with a fully-ranked Magnum Force. Keep in mind however that the accuracy bonus from Targeting Subsystem will only take effect once you hit an enemy and will only apply when you are aiming.
  • If a pistol already has a max rank Mod TT 20px Hornet Strike, adding a max rank Magnum Force represents only a ~54.6392% increase in damage per shot, compared to a 90% increase for a max rank uncommon elemental mod such as Mod TT 20px Heated Charge.
  • However, the Angstrum Angstrum can benefit from this, as it allows its charged shots to cover a larger area at the cost of limiting long-range capabilities. Alongside it are other secondaries such as Zakti Zakti, Talons Talons, Castanas Castanas, Staticor Staticor, Stug Stug, Sonicor Sonicor, Pox Pox, and Kulstar Kulstar when equipped with Multishot mods.
  • This mod also fixes the inaccuracy bug that occurs when using multishot on the Castanas Castanas and SanctiCastanas Sancti Castanas at low level, but it's still advised to max the mod anyway for extra damage and higher spread on the Castanas, leading to more crowd control.
  • This should only be used on weapons that already have Mod TT 20px Hornet Strike installed, as the bonuses gained from this mod are greater than Magnum Force and comes with no accuracy penalty. Also take Mod TT 20px Augur Pact into consideration as it costs less mod capacity without the accuracy penalty.

Trivia[]

  • When it was first released, Magnum Force increased recoil as well as damage. However the recoil penalty did not affect recoil-less weapons (Acrid Acrid, and Embolist Embolist, among others). This was confirmed to be unintentional in Warframe Prime Time - Episode 2 (9:40). The mod's effects were changed in Update 10.4 (2013-10-16) to give weapons an accuracy penalty instead of a recoil penalty.
  • "Magnum Force" is the name of the second movie in the "Dirty Harry" series of films starring Clint Eastwood.
  • Prior to Hotfix 24.2.10 (2019-01-23), Magnum Force provided +66% damage and -33% accuracy at max rank.
