About This Damage Calculator

Granblue Fantasy: Relink's damage system is a complex interplay of stats, sigils, and buffs. This calculator is designed to be the ultimate theorycrafting tool for dedicated players who want to see the real impact of their build choices. We cut through the complexity to give you clear, accurate damage numbers. By simulating the game's damage formula, you can confidently compare different sigil loadouts, see the value of a Terminus weapon, and understand how buffs affect your output without spending hours hitting a training dummy. This tool is built for speed, accuracy, and ease of use, making it an essential resource for optimizing your favorite characters.

How to Use
