Umbra Mods

Umbra Mods are a class of Legendary mods, that feature the properties of both Primed Mods and Set Mods. All are a superior variant of a standard mod, while also possessing a second stat that grants enhanced effectiveness when fighting Sentient enemies. They are divided in sets, but the Set Bonus of each set is the same: an increase of each mod's bonuses. Umbra mods are acquired through the The Sacrifice quest (and can thereafter be reacquired via Cephalon Simaris). They are untransmutable and untradeable. All Umbra mods have the exclusive polarity that can only be applied with an Umbra Forma. Visually, Umbra mods are Legendary mods with a set indicator.
