JoJo’s Bizarre Adventure GS: Gacha Rates, Pity System & Reroll Strategy Guide

Navigating the gacha banners in JoJo’s Bizarre Adventure GS can be intimidating for both new and veteran players.

Gacha Drop Rates & Pity Mechanics Explained

Understanding the summon probability and safety nets will help you plan your pulls and avoid wasting Gems on suboptimal banners.

Base Drop Probabilities

The standard drop rates for character recruitments are structured as follows:

SSR Units: 2.00% Base Rate
SR Units: 18.00% Base Rate
R Units: 80.00% Base Rate

Pity Thresholds & Safety Nets

To prevent bad RNG streaks, the game features three distinct pity mechanics that carry over between specific banner types:

60-Pull Soft Guarantee: Reaching 60 total pulls on any banner guarantees at least one random SSR character. Due to this mechanic, the effective average rate for pulling an SSR rises from 2.00% to 2.85% per cycle.
180-Pull Event Selector (Hard Pity): On limited rate-up banners, accumulating 180 summons rewards you with an Event Selector Box, allowing you to directly pick the featured banner SSR.
300-Pull Standard Selector: On the Permanent Standard Banner, reaching 300 total recruitments unlocks a Standard Selector Box to choose any non-limited launch SSR.

The 30-Pull Starter Banner Strategy

Upon completing the early campaign tutorial, every player unlocks a special beginner banner that allows you to perform 30 pulls with a guaranteed SSR outcome.

How the Starter Selector Works

This banner allows you to reroll your 10-pull results up to 30 times and lock in your favorite outcome before confirming your final choice.

Top Priority Targets to Lock In

When rolling on this beginner banner, prioritize locking in one of the following high-impact SSRs:

Priority	Target Unit	Role	Strategic Advantage
Pick 1 (Highest)	Caesar Anthonio Zeppeli	Ranged / AOE	Unrivaled early-game wave clear. Bubble detonation mechanics shred story boss health pools instantly.
Pick 2 (Alternative)	Giorno Giovanna	Special / Support	Future-proof support unit providing 5-second area immobilize, 40% damage-taken debuffs, and team-wide healing.
Pick 3 (Alternative)	Koichi Hirose	Special / Control	Infinite crowd-control chain loops that prevent high-level campaign enemies from executing their ultimate attacks.

Fast Reroll Method (Step-by-Step)

If your initial free pulls do not yield a top-tier combination, executing a quick account reset takes under 8 minutes per cycle when following this route:

1. Guest Account Login

Launch the game and choose the Guest Login option. Do not link your Google, Apple, or social media accounts during this initial phase.

2. Tutorial Acceleration

Complete the Prologue battle and skip all non-mandatory cutscenes. Follow the mandatory campaign prompts through Stage 1-4 to unlock the home menu and mail system.

3. Claim Milestone & Launch Rewards

Open your in-game Mailbox to collect all pre-registration rewards, milestone gifts, and compensation items. This grants you free Destiny Cards and standard Gems.

4. Execute Summons Sequence

Perform your pulls in the following exact order for maximum efficiency:

First, execute the 30-Pull Starter Selector until you lock in Caesar or Giorno.
Next, spend your free Destiny Cards on the active Limited Rate-Up Banner.
Finally, spend remaining Gems on the Standard Banner to hit early pity.

5. Account Reset Procedure

If you fail to land at least two top-tier units (1 SSR from starter + 1 key SR like Hol Horse or Speedwagon):

Go to Game Settings from the main menu.
Select Account Center and click Delete Guest Data.
Restart the game client and log in as a fresh Guest to repeat the process.

When Should You Keep Your Account?

A successful reroll account should ideally contain either 2 SSR units (e.g., Caesar + Giorno/Jonathan) OR 1 Top-Tier SSR + 2 High-Tier SR Budget Gems (e.g., Caesar + Hol Horse + Speedwagon). Once you hit this milestone, stop pulling and save your remaining Gems for future limited event banners!
