Most equipment slots accept any type of Mod. However, some slots are “polarized.” Each type of Polarity has a unique symbol. Polarities include:
- Madurai - V (Damage, Powers) - Commonly dropped by Grineer.
- Vazarin - D (Defensive, Health, Armor) - Dropped by all factions.
- Naramon - Dash/Bar (Misc.) - Commonly dropped by Corpus.
- Zenurik - Scratch (Warframe Augments and Channeling Mods).
- Penjaga - Y (Companion Abilities) - Dropped by all factions.
- Unairu - R - Introduced in Update 13.0 and used for certain Melee Stance Mods.
A mod's polarity type is noted in the top right corner of its card. When a mod is placed into a matching polarity slot, the cost of installing the mod will be reduced by 50%, rounding up to the nearest whole number. In contrast, placing a mod in a slot with a different polarity will increase its cost by 25%. This cost is rounded to the closest integer.
For Aura and Stance mods, polarities increase or decrease the amount of bonus mod points that the mod provides: matching polarities will increase the bonus mod points by 100%, while non-matching polarities reduce it by 20%.
A Warframe's polarity slots differ from the slots of other Warframes. This makes certain mod builds more efficient on certain frames.
- Main article: Polarization
Players may use Forma, a rare item obtainable from Void Fissure missions or the Market, to add or change a polarity on a piece of equipment that has attained rank 30. This increases the weapon or frame's overall strength by increasing the possible mod combinations that may be placed on it. Using Forma to add/change a polarity slot will reset the equipment's rank to zero, requiring the equipment to be leveled up again. Additionally, polarization allows players to rearrange polarity slots as they see fit, including polarities that were built into the equipment to begin with. As of Update 15.1, the aura slot's polarity cannot be swapped with another slot's.
Currently, there appears to be no cap on the number of times a weapon may be 'polarized' or what polarizations are possible (on a weapon with eight blank slots, you could polarize it eight times with the same polarity if you so wish) though good judgement on how you wish to build a weapon undoubtedly means variety will serve most Tenno well.

- It is apparent to those who know the Orokin Script that some Polarities are in fact the same symbols as some numbers and vowels, either rotated or flipped:
- Madurai () is the numeral 4, or an upside down 2.
- Vazarin () is the numeral 5 flipped vertically, or an upside down 3.
- Naramon () is similar to the symbol for 1, rotated 90° counter-clockwise.
- Zenurik () is the vowel "I" (as in the word "Pit") rotated 90° counter-clockwise.
- Penjaga () forms the number 10.
- Unairu () does not have a perfect connection to the Orokin Script, though Unairu is perhaps similar to the shape of the vowel "AYE" (as in the word "Price").
- According to Devstream 55, the names of the polarities correspond to old Tenno schools. These names are also used for the clusters depicted in the Star Chart 3.0 prototype also featured in the same Devstream.
- Up until Update: The Silver Grove, there was also a Koneksi () polarity that was reserved for Fusion Cores, which have since been superseded by Endo.
- In line with the naming schemes used by the other polarities, Koneksi does not have a perfect connection to Orokin Script, but it does bear similarities to the vowel "OH" (as in the word "Goat"). Similar to Penjaga, Koneksi is also Indonesian in origin, in this case translating to "connection", reflecting how Fusion Cores were the only mods that bore this Polarity.
