Malignant Force is additive with similar mods. For example, a Snipetron with a max rank Malignant Force and Rifle Aptitude will have a 20% × (1 + 60% + 90%) = 50% status chance.
This mod can be combined with High Voltage, Thermite Rounds and Rime Rounds to achieve a combined status chance bonus of 240%. With Rifle Aptitude and Hammer Shot, this bonus can be increased to 410%, more than quintupling the weapon's status chance.
