Bahamut becomes available exclusively through triumph in Chadley’s Combat Simulator. However, accessing this climactic confrontation requires clearing all 19 preceding Battle Intel objectives—a substantial time investment. While most tasks will naturally progress through regular gameplay, several demand focused effort and strategic planning. Below you’ll find the complete catalog of Chadley’s research requirements:
- Report 01: Monster Bio Pt. 1
- Assess two distinct enemy types using the Assess materia
- Assess two enemy types
- Report 02: Magic Elements Pt. 2
- Strike enemies vulnerable to fire, ice, or lightning elemental attacks using corresponding magic spells—one successful vulnerability hit for each element type.
- Hit enemies vulnerable to fire, ice, or lightning using the appropriate magic–one for each element.
- Report 03: The Stagger Effect Pt. 1
- Execute character-specific abilities against Staggered enemies and accumulate 10 full ATB gauge charges during combat.

Pro Tip: For efficient Battle Intel completion, prioritize the Assess materia early and consistently scan new enemies. Understanding enemy weaknesses through assessment data dramatically accelerates your progress through elemental and stagger-based objectives. Many players underestimate the time savings from systematic enemy analysis before engaging in combat.
Common Mistake: Attempting Bahamut without fully upgraded weapons and maxed materia. The damage output and survival requirements for this fight demand optimized gear—don’t rush the preparation phase.
When you finally confront Bahamut, preparation becomes your greatest ally. This boss employs devastating area-of-effect attacks and possesses a countdown mechanic that will wipe your party if not properly managed. Equip materia that provides healing, revival, and barrier effects alongside your strongest offensive spells.
Bahamut’s most feared ability, Megaflare, activates after a visible countdown reaches zero. You must either defeat him before this occurs or utilize specific defensive strategies to survive the inevitable devastation. Mastering interrupt techniques and maintaining constant pressure are essential for victory.

Advanced Tactics: Coordinate your party’s limit breaks to activate during Bahamut’s countdown phase. Proper timing can either prevent Megaflare entirely or mitigate its catastrophic damage. Consider pairing this guide with our comprehensive Weapons Unlock strategies to ensure your arsenal matches the challenge ahead.
