Using Umbra Forma on EquipmentEdit
To apply an Umbra Forma, go to the Arsenal and access the desired Warframe's Mod loadout. Select Action at the bottom of the screen, then choose Polarize, which will show all available type of Forma to choose from. Choose Umbra Forma, which will show a layout of the item's mod slots and polarities. Click on a slot to polarize with Umbra polarity. A slot that already has a polarity (either by default or from a prior polarization) can also be changed.
- Umbra Forma cannot be used to polarize a Warframe's Exilus or aura slot.
- Umbra Forma can only apply Umbra polarity, and cannot be used to apply other polarities.
- While players can Umbra Forma any equipment and the description also includes Companions, only Warframes and Melee weapons have Umbra Mods available.
- The Helios /Helios Prime weapons (Deconstructor and Deconstructor Prime ) are the only Companion Weapons able to utilise Umbra Mods.
