This is a special stat for Musashi.
Here's how it works so far: Musashi can find various monster tracks in the Forest (The Pheromones increase the chance.) To catch it, she needs the Call that would lure that monster, Narcotic Bait to tranquilize it, and on returning to the Forest in another turn, a Monster Ball to hold it. The amount of bait to use may depend on Monster Hunting statistic. The Monster Balls, Calls, Narcotic Baits and the Pheromones are buyable in the A.T.E.A.M. Base.
Common Monsters worth 1000 GP, Uncommon worth 1500 GP, and Rare worth 2500 GP.
