2. Phase 1 – Opening Attacks and Initial Patterns

Key Attacks & How to Deal With Them

Attack	Description	How to Avoid
Dive & Pound	Bahamut flies up and slams into the ground.	Jump over the shockwave, do NOT block it.
Purple Debuff Attack	Inflicts a stacking debuff—getting hit again will trigger an explosion.	Avoid getting hit twice in a row with the same element.
Flying Laser Sweep	A large laser sweeps across the arena.	Block instead of dodging to avoid unnecessary risk.
Rotating Circle AoEs	Explosions expand outward in a pattern.	Move to the outer edges for safety.
Beam Slam	A ground explosion follows his beam attack.	Jump to avoid the shockwave.

Survival Tips for Phase 1

• Never block the Dive & Pound attack—always jump over it.
• Positioning is key: Stay near the edges to avoid being trapped in AoEs.
• If unsure, prioritize blocking over dodging—some attacks are more reliably blocked.

3. Phase 2 – DPS Check & Advanced Mechanics

At the end of Phase 1, Bahamut initiates the first DPS check.

How to Handle the First DPS Check

1. When the cutscene starts, you’ll always spawn directly in front of Bahamut.
2. Use all buffs immediately.
3. Initiate a full Chain Burst using your SBA. (The timer will pause during SBA animations, giving you extra time.)
4. If you fail the check, he will unleash a powerful attack that deals massive damage.

If you succeed, the fight will continue into Phase 2 with faster, more aggressive attack patterns.

4. Phase 2 – Harder Attacks & Final DPS Check

New Attack	Description	How to Avoid
Rotating Wall & Expanding Circles	Walls rotate around the arena while expanding AoEs spawn.	Run left, jump over AoEs, and dodge through walls.
Instant Kill DPS Check	Happens when Bahamut reaches 10% HP.	You must defeat him during this phase, or he will unleash an unblockable attack.

How to Handle the Final DPS Check

1. At 10% HP, Bahamut will stop normal attacks and begin his final DPS check.
2. Use SBA and Link Time together for maximum damage.
3. Failure to kill him in time will result in a guaranteed wipe.

5. Key Mistakes & How to Avoid Them

Common Mistakes:

• Dodging when you should block: Some attacks are easier to block than dodge.
• Not saving SBA & Link Time: You must save them for the second DPS check.
• Failing to manage the purple debuff: If you get hit twice by the same element, you will take explosive damage.
• Running out of stamina from excessive dodging: Dodging too many times in succession will trigger a stagger state, leaving you vulnerable.

Final Tips

• Jump over the Dive & Pound attack every time.
• Position yourself properly before AoE attacks—outer edges are usually safest.
• Perfect Dodge is possible but risky—blocking is more reliable.
• Save all major cooldowns and SBA for DPS checks.
