The key phrase refers to a tool, often web-based or downloadable, used to compute the Attack Rating (AR) of weapons within the original Dark Souls game. Attack Rating represents the damage a weapon inflicts upon a successful hit, factoring in base damage, scaling with player stats (Strength, Dexterity, Intelligence, and Faith), and other relevant modifiers. For example, a player might use this tool to determine the AR of a Claymore +15 with 40 Strength and 40 Dexterity.
Such instruments are vital for character optimization and build planning within the game. They enable players to make informed decisions regarding weapon selection and stat allocation, maximizing damage output. Historically, these calculators arose from a need for precision, as the game itself provides limited information about the precise AR calculations. Players desired to understand the numerical impact of various upgrades and stat investments, leading to the creation of these community-driven resources.
