To effectively defeat BALTEUS in Chapter 1 of Armored Core VI: Fires of Rubicon, it’s essential to focus on a strategy that maximizes your offensive potential while leveraging mobility and understanding BALTEUS’s attack patterns. Here’s a comprehensive strategy breakdown to help you succeed.

Key Weaknesses and Build Recommendations

Recommended Loadout:
– Right Arm: Pulse Gun
Critical for shredding BALTEUS’s pulse shield. The Pulse Gun’s rapid-fire capabilities can significantly deplete the shield when used correctly.

– Left Arm: Plasma Blade
Ideal for inflicting high melee damage after staggering the boss, especially when the shield is down.

– Back Weapons: Dual Missile Launchers
These provide good tracking capabilities, essential for maintaining pressure while evading BALTEUS’s attacks.

– Legs: Bipedal
Offers balanced speed and stability, allowing for agile maneuvers during combat.

– Boosters: Quick Boost
Prioritize boosters that enhance quick boosts for efficient dodging, vital for evading attacks.

– Core/Arms: High AP (HP)
Choose components with high armor points to withstand barrage from missiles and other heavy assaults.

Phase 1: Shield Break and Stagger

1. Aggressive Rushdown:
Initialize your approach by closing the distance as quickly as possible. This tactic reduces the effectiveness of BALTEUS’s missile tracking systems, giving you a window to engage.

2. Pulse Gun Focus:
Upon reaching close range, focus your fire on BALTEUS with the Pulse Gun. Accept potential overheating, as dealing damage to the shield is your priority.

3. Stagger Punish:
Once BALTEUS’s pulse shield is broken:
– Immediately switch to your Plasma Blade and unleash charged melee attacks to inflict substantial damage.
– Simultaneously, fire missiles during the stagger window to maximize damage output and capitalize on the boss’s vulnerable state.

Phase 2: Missile Hell and Flame Attacks

After BALTEUS reaches 50% HP, it will enter a more aggressive phase characterized by devastating attacks.

– Missile Swarm:
– Stay airborne and utilize quick horizontal boosts to dodge clusters of missiles effectively.
– Whenever possible, use surrounding buildings or terrain for cover to mitigate damage from missile barrages.

– Flame Thrower:
– As BALTEUS prepares to use its flame attack, backpedal rapidly to maintain distance and avoid damage.
– If cornered, execute a vertical boost over BALTEUS to escape its melee range and reposition yourself for a counterattack.

Additional Tips

– Assault Boost:
Use the assault boost strategically to quickly close distance after BALTEUS dashes away, maintaining pressure and control.

– Energy Management:
Carefully manage your energy (EN) consumption; overusing energy-based weapons can leave you vulnerable, especially when dodging critical attacks.

– Alternate Builds:
If Pulse Guns are unavailable, consider using plasma rifles, understanding that the shield break will require more time compared to the dedicated Pulse Gun approach.

For enhanced understanding and visual guidance, consult timestamped boss fight breakdowns in various Chapter 1 guides. This will provide you with a clear perspective on timings and positioning during the encounter.

By following these strategies and adjustments, you’ll increase your chances of overcoming BALTEUS and progressing smoothly in Armored Core VI: Fires of Rubicon. Good luck!
