There's a satisfying finality when you max out every weapon upgrade in a game. No more scrounging for rare materials or hoarding currency; every gun, blade, or staff hits its full potential. That damage number isn't climbing anymore—it's peaked, and you know exactly what each tool can do at its absolute best.
