Lucky Defense! Infection Shell 67M+ Raid Strategy

To surpass 67 million damage against the Infection Shell in the Lucky Defense! Guild Raid, prioritize continuous armor shred, cluster your board around Kitty Mage mana batteries, and field single-target Mythics with percentage-health scaling before the boss enrages.

Core Raid Team Composition

The Infection Shell possesses high base defense and ramping damage reduction shields that blunt raw attack power. Overcoming this mitigation requires dedicated debuffers and rapid skill cycling rather than wide-area damage dealers.

Armor Shredding Requirements

Unbuffed guardians hit the Infection Shell for only a fraction of their listed damage. Stacking armor reduction brings the boss to a vulnerable state where your DPS multipliers can function.

1. Maintain Two Independent Sources: Deploy at least two shredding guardians, such as Hunter and Coldy. Running duplicate or split shred sources prevents defense gaps while units are caught in cast animations or attack recovery.
2. Anchor debuffers on the attack path: Position your shred units directly along the boss's strike line. If a debuffer is displaced or falls out of range, the boss immediately re-establishes its damage reduction, dropping board output.

Mana Generation and Skill Rotations

Single-target Mythic units rely on active skills that have long base cooldowns. Continuous skill uptime is required to capitalize on defense-shred windows.

• Cluster Around Kitty Mage: Position Kitty Mages adjacent to both your primary debuffers and your burst DPS units. The mana regeneration aura forces frequent skill activations.
• Synchronize Procs with Shred Windows: Accelerated mana flow allows percentage-based damage skills to trigger multiple times while armor break is active, preventing wasted skill casts during mitigation phases.

Carry Selection: Single-Target vs. Wave Clear

Guild Raid attempts are strictly time-gated, and board capacity is limited. Every unit slot must directly contribute to single-target boss damage.

• Prioritize Current-HP Scaling: Lancelot serves as the primary burst option because his damage scales against massive raid health pools, turning the boss's high durability into offensive yield.
• Add Focused Finishers: Complement percentage damage with Batman or a leveled Chu to maintain consistent damage when the boss reaches lower health thresholds.
• Avoid Area-of-Effect Mythics: Do not merge or summon wide-area clearers such as Iron Mecha. Wave-clearing specialists lack the focused multipliers needed to reach the 67-million-damage benchmark.

In-Match Economy and Board Management

Maximizing damage within the raid timer requires disciplined board merges and shop investments from the start of the encounter.

1. Secure Core Fusion Materials First: Spend early summons acquiring the common and rare materials needed for your essential Mythic recipes. Avoid gambling on speculative, off-target summons early on.
2. Upgrade the Enhancement Shop: Invest in flat attack power upgrades through the enhancement shop parallel to your board progression to match the boss's scaling stats.
3. Prune Suboptimal Units: In the late phase, clear out low-tier leftovers and unaligned support units to free up board tiles. Use the reclaimed space for extra Kitty Mage batteries or supplementary armor shredders.
