A new exotic weapon was not in the database: a sword.
Five exotic weapons were newly found in the database with Rise of Iron. A sixth has now been found. It is Wolf’s Howl, a Solar Exo sword.
You get this thing by simply completing the new campaign until the end. The campaign is called “The Dawning of the Iron Lords,” the sword step is number 11 “The Iron Grave.” There you finish “Remnants of Felwinter” with a fire axe. Then in a cutscene, Lord Saladin himself appears and hands over the sword, it has a medieval vibe.
The sword itself has two options to modify it with ornaments. Especially “Fire-forged” looks nice. The ornaments can be obtained through the new treasure boxes “Radiant Treasure” – you can earn one per week by playing the heroic Siva playlist – or you can buy it in Eververse.
