JoJo's Bizarre Adventure: GS Cool Ice Boss High Score Guide

To achieve a high score against Cool Ice in the Iggy event in JoJo's Bizarre Adventure: GS, replace defensive units with high-burst damage dealers, trap the boss against arena walls to limit mobility, and save all ultimate abilities to unleash simultaneously when the boss enters a downed state.

Team Composition Strategy

Cool Ice functions as an event damage sponge with a limited fight timer, making survival stats unnecessary for leaderboard runs. Focus your team selection entirely on offensive output:

• Primary Damage Dealers: Select units capable of fast, burst damage rotations rather than slow, channeled attacks that leave you vulnerable when the boss moves.
• Buffer and Debuffer Support: Bring units that apply team-wide attack buffs or inflict defense debuffs on the boss to increase your main attacker's damage output.
• Units to Avoid: Omit dedicated healers, tanks, and sustain characters, as defensive utility sacrifices the raw damage required to reach top score tiers.

Your score scales directly with your roster's stat threshold. If your roster lacks deep resources, focus your ascension and imprint upgrades on your primary burst damage dealer rather than spreading upgrades across secondary units.

Positioning and Boss Control

Cool Ice moves rapidly across the arena, which can waste skill cooldowns if your units spend time walking into range. You can minimize downtime by controlling where the boss lands.

1. Force Arena Edges: Push Cool Ice toward the boundaries of the arena. Cornering the boss restricts the distance it can travel during dash and invulnerability phases, keeping it within range of your team.
2. Preposition for Dashes: Watch the boss's dash animations to identify its trajectory. Move your units toward the projected landing point before the animation ends so your team can attack immediately upon arrival.
3. Dodge Knockback Attacks: Use mobility skills exclusively to dodge telegraphed area-of-effect (AOE) attacks. Getting hit results in knockbacks that halt your damage output and decay your combo multiplier.

Ultimate Syncing and Break Phase Rotations

Managing your energy and skill timing around boss vulnerability windows provides the largest point yield in this encounter.

• Hold Ultimates for Downed States: Do not fire ultimate abilities as soon as they charge. Wait until Cool Ice's status indicator shows a "broken" or "downed" state before triggering your skills.
• Execute Buffs Before Burst: Activate team attack buffs immediately before launching your primary damage dealer's ultimate to ensure the burst benefits from the active multiplier.
• Avoid Basic Attacks During Breaks: Avoid using basic attacks during a break window; reserve full energy reserves to cycle high-damage abilities in rapid succession.
• Maintain Single-Target Focus: Confirm all units are target-locked directly onto Cool Ice so damage is not split or wasted on secondary targets.
