SD Gundam G Generation ETERNAL: Best Dev Units to SSP for South Tower

To clear higher floors in the South Tower without burning out your premium banner roster, allocate scarce Super Special Potential (SSP) upgrades to the Freedom Gundam and Turn A Gundam first, followed by the Zeta Gundam as an evasion specialist.

Higher floors in the South Tower enforce strict deployment restrictions and lockout mechanics that quickly exhaust standard gacha collections. Farmable Development units offer a sustainable alternative, but their base forms frequently suffer from defensive and offensive stat deficits that risk lethal one-shot counters on floors 10 through 15. Applying SSP upgrades bridges this gap by boosting base stats, survival thresholds, and skill potency to endgame levels.

Top Development Units for SSP Enhancement

1. Freedom Gundam (Long-Range and Multi-Target Sweeper)

• SSP Priority: Tier 1 (Immediate)
• Role: Minion wave clearing and safe perimeter bombardment
• Key Strengths: Extended range (4–5 tiles) and multi-lock MAP attacks (Hi-MAT Full Burst)
• Operational Drawback: Heavy EN consumption over prolonged multi-phase battles

Upgrading the Development Freedom Gundam with SSP increases its shooting attack and EN pool, enabling it to eliminate escort clusters before enemy formations close in. Attacking from range 4–5 allows it to neutralize threats without triggering lethal close-range counterattacks. To mitigate its fast EN drain, deploy the Freedom Gundam near command aura units or EN-replenishing support crew.

2. Turn A Gundam (Frontline Sustain and Attrition Tank)

• SSP Priority: Tier 1 (Immediate)
• Role: Choke-point holding and self-healing frontline anchor
• Key Strengths: Nanomachine health regeneration and Moonlight Butterfly crowd debuffs
• Operational Drawback: Low burst mobility and slower clear pace

Stages with continuous reinforcement waves punish squads that lack self-sustain. The Turn A Gundam features passive nanomachine regeneration that restores a percentage of maximum health at the start of each turn. Granting SSP raises its maximum HP pool, directly scaling the total health recovered per turn. Its Moonlight Butterfly skill also softens incoming damage across enemy formations. Avoid deploying it as a primary attacker on floors with strict turn-count limits.

3. Zeta Gundam (High-Mobility Evasion Duelist)

• SSP Priority: Tier 2 (Secondary)
• Role: Single-target boss baiting and critical counter-striker
• Key Strengths: Bio-Sensor stat thresholds, high baseline maneuverability, reliable beam weapons
• Operational Drawback: Drastic loss of evasion in unfavorable terrain

Upper South Tower bosses hit hard enough to pierce high-armor tanks in one or two rounds. The Zeta Gundam bypasses raw incoming damage by driving boss hit rates into the single digits once its Bio-Sensor activates. Elevating its mobility and reaction stats through SSP turns it into a premier bait unit that dodges incoming fire and retaliates with high-critical strikes. Verify stage terrain affinities before deployment, as poor terrain ratings neutralize its evasion advantage.

Next Steps Before Committing Resources

1. Attempt the Floor Unupgraded: Run your intended stage with standard level-capped units first. Adjust pilot positioning, support aura placement, and skill timing to confirm whether tactical changes can clear the floor without resource expenditure.
2. Diagnose the Failure Point:

• If your team wipes to clustered escort groups, upgrade Freedom Gundam.
• If frontline attrition wears down your squad over extended turns, upgrade Turn A Gundam.
• If a single boss eliminates your front line in one turn, upgrade Zeta Gundam to bait incoming attacks.

1. Commit Upgrades Individually: Apply SSP to one unit at a time to preserve rare materials for subsequent lockout stages.
