To clear the Submerged Era Armed Conquest stage on Inferno difficulty in Mecharashi using a free-to-play roster, lead your turns with defense-down debuffs to break boss armor, preserve action points for vulnerable vulnerability windows, and spread your mechas across the grid to avoid wide-range attacks.

Inferno difficulty demands strict turn economy and defensive spacing rather than raw unit rarity.

Action Point Economy and Team Structure

Clearing high-HP Inferno bosses without premium banners requires selecting units based on tactical utility rather than base rarity. Build a balanced squad capable of executing a strict debuff-and-burst rotation:

  • Armor Strippers: Use mechas with reliable defense-down debuffs or armor-shredding skills first in your turn sequence. Breaking the boss's shields opens up the target for your primary damage dealers.
  • Secondary Damage Dealers: Hold high-cost attacks until after armor reduction is applied.
  • Action Point (AP) Preservation: Avoid using high-cost skills on minion spawns or non-essential targets. Conserve AP so your mechas can launch full combo turns when bosses enter stunned or weakened states.

Grid Positioning and Defensive Spacing

Bosses on Inferno difficulty hit hard enough to wipe clustered squads with wide-area attacks. Maintain tactical grid control through defensive placement:

  1. Spread Out Squad Members: Position units across different lanes so wide-range attacks hit only one or two mechas at a time. This enables support or healer units to manage single-target damage without the team taking full area damage.
  2. Use Terrain and Obstacles: Place fragile attackers behind cover or block straight sightlines. Forcing bosses to take longer routing paths grants extra turns to recharge abilities and reposition support mechas.
  3. Evade Telegraphs: If a boss telegraphs a lethal heavy strike, move targeted units out of the threat zone rather than attacking. Maintaining full unit headcount across turns is essential to beating turn limits.

Managing the Blazetrudge Encounter

The Blazetrudge encounter is a major endurance check due to the boss's high durability and counter-attack patterns.

  • Pacing: Avoid blowing all cooldowns on early turns. Track the boss's attack pattern to identify safe phases for offensive pushes.
  • Chip Damage: Rely on basic abilities and consistent ranged poke damage to whittle down armor plates during aggressive boss phases.
  • Execution Phase: Save ultimate skills and heavy burst combos for when Blazetrudge is immobilized or stunned by your team's support skills.

Next Steps: Post-Clear Upgrades

Once you complete the Submerged Era bosses, reinvest your event clear rewards directly into your primary roster:

  • Upgrade core team mecha equipment to meet higher damage and durability checks.
  • Unlock relevant Neural Drive nodes for your primary armor strippers and supports to improve AP generation and debuff uptime.
