Corrupted Mods

Corrupted Mods are a class of rare mods that affect one stat beneficially (a bonus) and another one detrimentally (a penalty). Those available for Warframes are characterized by extremely high bonuses outweighed by major penalties. Those available for weapons provide bonuses of a similar strength to their standard mod analogues, while still also having a penalty. Corrupted mods can be obtained from the Orokin Derelict tileset on Deimos (not to be confused with the Orokin Tower tileset on the Void) using special Dragon Keys to unlock Orokin Vaults located within. They are untransmutable. Visually, they do not have any special distinguishing mark and appear as any other mod of Rare rarity (i.e. gold-colored).

• Corrupted mods that provide a bonus to Critical Chance (e.g.  Critical Delay) are a notable exception to the general pattern of nonstandard mods in that they cannot be stacked with their standard analogues.
• There are currently 24 Corrupted Mods and each of them has an equal chance to drop (4.1667%).
