SD Gundam G Generation ETERNAL: South Tower 12F 3-Unit Dev Clear

To clear South Tower 12F in SD Gundam G Generation ETERNAL using only farmable development units, deploy a three-unit squad divided into frontline defense, mid-range support, and burst execution. Because development suits lack the inflated stats and wide-area map attacks of premium gacha units, your immediate tactical action is to draw individual vanguard enemies away from rear artillery lines and eliminate them before they converge.

Required Three-Unit Roster Composition

A three-unit clear requires strict functional separation. Each mobile suit and its assigned pilot must fulfill an exclusive role so your team can survive multiple skirmishes without incoming damage overwhelming your limited squad size.

Assign pilots whose passive terrain ratings match the Floor 12 environment. Giving a mobile suit a pilot with an A-rank terrain rating provides vital hit-rate and evasion bonuses that offset baseline stat deficits against high-floor tower opponents.

Turn-by-Turn Baiting Sequence

Floor 12 punishes aggressive forward movement due to overlapping enemy firing lanes and long-range snipers. Never end a phase where multiple hostiles can target the same friendly mobile suit. Use this sequential positioning loop to pick off targets cleanly:

1. Set the Initial Lure: Move your frontline anchor exactly one square inside the attack range of the nearest hostile unit. Station your marksman and burst striker one tile behind your anchor, keeping both outside all enemy threat zones.
2. Soak the Enemy Phase: Let the baited enemy target your anchor. Choose Defend or Guard instead of counterattacking if retaliating risks reducing your anchor's HP below safe thresholds.
3. Execute the Crossfire: Open your player phase by attacking with your mid-range marksman from maximum range to soften the target's armor. Follow immediately with your burst striker to deliver the kill, removing the enemy before it acts again.
4. Advance to Chokepoints: Reposition your three units toward terrain cover or narrow map corridors to limit enemy flanking angles on subsequent turns.

Morale and Skill Point Management

Maintaining offensive momentum with three units depends on cycling the Tension gauge while strictly conserving pilot Skill Points (SP):

• Funnel Kills to Your Striker: Because a three-unit squad has fewer total actions each round, funnel last hits directly to your burst striker. Advancing pilot Morale through Strong and Super Strong to Super High Tension ensures guaranteed critical strikes on standard attacks, providing high damage without wasting resources.
• Hoard Active SP for Boss Encounters: Free development pilots have smaller SP reserves and limited recharge opportunities. Avoid spending SP on standard stage minions; save stat boosts for the floor boss, or use them only when a defensive evasion skill is mandatory to prevent a unit loss.

Pre-Battle Unit Preparation

Before starting South Tower 12F, maximize the mechanical stats of your three development units to bridge the gap against high-tier tower enemies:

• Upgrade Modification Levels: Use upgrade chips to raise weapon power and base HP to the current stage cap, ensuring each unit can withstand at least two non-critical hits.
• Verify Terrain Proficiency: Confirm that all three mobile suits possess an A-rank proficiency for the stage's terrain to avoid movement penalties and base dodge reductions.
• Assign the Master Slot: Place your highest-impact pilot or primary damage dealer into the squad's Master Unit position to secure full aura benefits and optimize operational performance across the squad.
