Warframehas plenty of weapons, companions, and Necramechs to build and perfect, and thanks to the help of Mods you can boost your stats and open the doors for extra benefits that you couldn’t acquire otherwise. Leveling up a mod is no easy feat tho, and some of them might demand a lot of Endo, the substance required to power them up.

One of the most rare and valuable resources is Legendary Cores, which allow you to max out any Mod without concerning yourself with the Endo Cost. However, getting your hands in one of them might be a challenge, and here we’ll tell you everything about it.

How To Get Legendary Cores

Legendary Cores are incredibly rare to obtain, but you can get them through the following activities:

Legendary Core Uses

Legendary Cores are used for one thing only, to level up any Mod to its maximum level without any Endo cost. This allows you to skip hard-leveling mods like the Umbra Mods for Warframes and Melee weapons, Galvanized Mods, or even Primed mods.

That being said, with how accessible farming Endo becomes as you progress through the game, it might be more useful just to keep the Legendary Cores in your inventory and then sell them for Platinum on the player market.
