Wraith

Wraith weapons are a special variant of existing weapons only given out as rewards from various limited-time Events, Tactical Alerts, and Invasions. Wraith weapons feature a shiny dark-blue paint scheme with patterns of red bars and lines, and have improved stats over the original weapons. While any weapon is eligible for Wraith treatment, currently known Wraith weapons are derived from Grineer and Tenno designs.
