GBF Artifact Scorer
An unofficial Chrome extension that scores Granblue Fantasy artifacts by your own rules and shows the results in the extension UI.
Before You Use It
This is an unofficial extension for desktop Chrome. You can read this page on mobile, but the extension itself is intended for desktop use.
It does not automate gameplay or make additional requests to the game server, but please decide for yourself whether to use it.
Overview
This extension lets you create scoring rules based on artifact effects, quality, element, and weapon specialty, then shows calculated scores in the extension settings page. It is a helper for sorting artifacts by your own criteria.
A bundled default configuration is applied on first use. You can freely edit it, export your settings as JSON, and import them into another browser profile.
Supported Environment
The current version is intended only for desktop Chrome and the Japanese game environment. Mobile, tablet, and English game environments are not supported at publication time.
What It Does
- Reads artifact list responses already loaded by the game page and calculates scores locally from your rules.
- Displays calculated scores, optional in-game scores, and score breakdowns in the extension settings page.
- Saves scoring rules, combination bonuses, and display preferences in Chrome local storage.
- Highlights high, normal, and low scores inside the extension UI based on your thresholds.
What It Does Not Do
- It does not automate gameplay, farming, upgrading, selling, selecting, or any other game action.
- It does not make additional requests to the game server or external services.
- It does not send artifact data, scoring rules, or browsing information to the developer server.
- It does not update the game page DOM, change the game UI, sync settings through a Google account, run analytics, or serve ads.
- It does not guarantee that scores represent in-game value or an optimal choice.
Data Handling
Artifact list data is processed temporarily in page memory and is discarded when the page is closed or reloaded. Scoring rules and extension UI display settings are saved in Chrome chrome.storage.local so they can be restored next time.
If you export a settings JSON file, that file is managed by you. It is not uploaded to this extension or to the developer server.
