These items are crucial for maximizing the mod capacity and efficiency of your gear:
- Orokin Catalyst (Weapons) / Orokin Reactor (Warframes & Companions): These rare items double the Mod Capacity of the item they are applied to. This is a permanent upgrade and is essential for fitting high-drain mods. They are often rewarded from Alerts, Nightwave, or purchased from the Market for Platinum.
- Forma: Forma allows you to add or change the polarity of a mod slot on a Warframe, weapon, or companion. When you apply Forma, the item's rank resets to 0, requiring you to level it up again. This is done to match mod polarities, effectively halving the mod's drain and allowing you to fit more powerful mods. Forma blueprints are commonly found in Void Relics and sometimes as quest rewards. You'll need many Forma for endgame builds.
Prioritize applying Orokin Catalysts/Reactors to your favorite and most used gear first. Use Forma strategically on items you intend to keep and optimize for high-level content.
