Using Forma on Equipment
To apply a Forma, click Arsenal and equip the desired item. Scroll over the item in the arsenal. Select Action at the bottom of the screen, then choose Polarize, which will show a layout of the item's mod slots and polarities. Click on a slot to cycle through the possible polarities. A slot that already has a polarity (either by default or from a prior polarization) can also be changed.

Forma can only be used on equipment that has already been ranked to 30 and, when used, said equipment is reset to rank 0 (unranked).Warframes and Warframe Skills will be reduced to rank 0. Forma can be used again on already polarized equipment, provided that it is leveled to 30 again. Orokin Catalysts and Orokin Reactors are unaffected by the usage of Forma. Re-leveling equipment after using Forma on it does not grant mastery points.

For each Forma used on equipment, said equipment will gain a star on the top right corner under the name of the equipment. The current UI can display up to 13 stars.

Trivia

 * Forma means "shape" in a variety of languages, including Latin, Spanish and Italian.
 * The Forma is shaped as a jigsaw piece.
 * The prevalence of golden surfaces in Orokin Void levels and on Prime equipment may indicate the use of massive amounts of Forma in their construction. The grey surfaces in the Clan Dojo may be due to Tenno improvising with more mundane materials while copying the Orokin aesthetics. The golden colors of the Orokin Reactor may also be due to the presence of Forma in this construct.
