Each Warframe starts with different polarity slots already, and depending on your play-style / who you started as, it will effect the outcome greatly. I am starting with this one, but it is the hardest to qualify. You cannot select them as slot upgrades with forma. Note: The final two polarities, although listed, are not used in this guide.I will break down what you should spend them on as far as polarity slots.ĭefense: Signified with an Upside Down Triangle. The reason for this is due to the rare drop of forma and forma patterns (I have cleared maybe 12-15 towers with friends and seen none), many if not most of us will be spending platinum on them.
In this guide, I will discuss how to use forma productively when upgrading your weapons, Warframe, and sentinel.
