Gacha Simulator FAQ
Q Is this Gacha Simulator linked to my Roblox account?
No, this is a **standalone simulator** for testing luck. Items pulled here do not transfer to your official Roblox Jujutsu Zero account.
Q What are the drop rates for Special Grade clans?
The drop rates are designed to match the in-game mechanics: **1% for Rare (👹)**, **5% for Special (🔵)**, and **14% for Grade 1 (💍)**. There is a pity system that guarantees a Grade 1 or higher every 50 spins.
Q How do I reset my collection?
You can click the **"Reset"** button in the luck stats section to clear your history and collection. This will delete all local data saved in your browser.
