Redefining the Power Couple is an Optional Quest in Monster Hunter World. In it, we're off to the Ancient Forest to hunt both a Rathalos and a Rathian, as a reward you'll receive the Bandit Mantel. A very useful specialized tool that while being worn gives your attacks a chance to cause the monster to drop rare trade-in items. This makes hunts while wearing the Bandit Mantel great for farming zenny.
