What is the definition of Necessary Weapon?

A 'necessary weapon' is like the ultimate sidekick in your survival game - it's there when you need it the most, but it's not exactly a superhero. Think of it as your trusty sidekick in the kitchen, always ready to slice and dice when you're whipping up a disaster (or a delicious meal). It's the secret weapon that keeps things from falling apart, but it's usually overlooked until the very end when you realize how much you rely on it.
