Polarization in Warframe is an important mechanic for getting the most out of your weapon, companion, and Warframe builds. You can polarize a mod slot, setting a new polarity of your choice, allowing you to play more powerful mods. Matching the polarity of a mod with the same polarity mod slots halves the mod capacity of that particular mod, allowing you to play lots of high capacity mods in the same build.
This is using an item called a Forma. To use a Forma, you need to go to your Arsenal, then click on the weapon, companion, or Warframe. Click on Actions in the bottom right of the screen, then Polarize. Select the Forma you want to use, then the slot you want to use it on. Finally, set the Polarity of the slot to the same Polarity as the Mod you wish to place in it by clicking on the slot to cycle through the different polarities. The item has to be Level 30 to use the Forma, and when you Polarize it, it will be reset to Level 0 again. You will need to level it up the same way you level up all other gear.
Remember, only Forma used outside of the Simulacrum will count toward this challenge. It is also a good idea to think about your overall finished build before committing a Forma to change a slot.
How to get Forma
You can get Forma in the game by opening Void Relics. The blueprints for Forma can drop from quite a few Relics in the game, and many are placed in the Common slot, making them quite easy to farm up.
You then build the Forma in the Foundry, with the following resources:
- 35,000 Credits
- 1 Morphics
- 1 Neural Sensor
- 1 Neurode
- 1 Orokin Cell
You can check what each Relic contains in the Void Relic console on the ship, the Codex, or at the start of a Void Fissure mission when you are picking which Relic to equip. While this is the most common way to get Forma, you can get it from other means. Forma Blueprints can drop as login rewards, or as rewards for completing Invasion Missions. They can also drop from finding all hidden caches in Earth Sabotage missions, although the chance of this is minimal.
There are also ways to get fully built Forma. Sometimes a Forma drops as a reward from the daily Sortie. During the Operation Plague Star, which is held sometimes on Cetus, you can purchase them from Nakak for 3000 Op Supply. This method is one of the best ways to get Forma blueprints and is a fantastic way to stock up on them.
If you need one, you can purchase a Forma from the Market for 20 Platinum, or a pack of three for 35 Platinum.
