Vaas' Wrath is the unique Mirror trait in the Vaas: Insanity DLC. It builds around takedowns, adding speed, reloads and small heals after each one, and its later levels let you take down alerted enemies and Heavies.
Each level makes takedowns pay off more. Early levels give a speed burst, slower enemy detection and a free reload. The top levels let you take down enemies who have already spotted you. The last one adds chain and sidearm takedowns on Heavies.
Walk up to the Mirror in a safe house and spend Cash, the currency you earn in Vaas: Insanity. Levels unlock in order, and each one costs more than the one before.
Yes for a stealth or close-range Vaas. Level 3 saves a lot of reloads, and the last two levels change how you can fight armored enemies.
