Now, levelling your gear simply increases how many mods you can fit on your gear, and the Reactor/Core increases that number significantly. Each piece of equipment had an RPG-like levelling-tree, which could be expanded dramatically by installing an Orokin Reactor or Core. During the closed beta, levelling your frame and your weapons actually DID something. While farming for foundry supplies was somewhat worthwhile before, it wasn’t needed, and mods weren’t your only means of building your character. It all comes down to the changes made with Update 7. With this guide, I’ll show you how to maximize your mod earnings per mission, as well as foundry crafting items and how to determine what alerts are really worth your time. With the release of Update 7, and the Steam release, Warframe’s player progression is more reliant than ever on you having a good selection of mods at your disposal.
