Knock Knock: Room Defense – How to Counter Boss Stat Scaling in Infinity City

In the Infinity City mode of Knock Knock: Room Defense, players often encounter a specific progression hurdle where enemy boss mechanics—particularly those involving life-locking and power-capping—can cause a massive difficulty spike. Understanding how to navigate these scaling limitations is essential for pushing through higher floors without stalling.

Understanding Boss Scaling Mechanics

As you progress through Infinity City, you will encounter bosses that utilize "Power Cap" or "Stat Lock" abilities. These mechanics are designed to neutralize your hero’s raw attack power, effectively forcing the boss's HP to remain static or regenerate despite your DPS output.

If you find that your damage numbers are dropping from significant values (e.g., 53) to negligible amounts (e.g., 20s) during a fight, you are likely hitting a hidden scaling threshold.

Strategic Adjustments for Stat-Locked Bosses

When a boss hits a state where your current team composition fails to break their life-lock, consider the following tactical adjustments:

Prioritize True Damage Over Raw Stats: If the boss has a mechanic that locks your Attack Power, raw damage increases will yield diminishing returns. Shift your focus toward heroes with "True Damage" or percentage-based health reduction abilities, as these are often calculated independently of standard stat-check thresholds.
Stagger Hero Deployment: Deploying all high-DPS units at once can sometimes trigger an aggressive scaling response from the boss AI. Attempt to stagger your deployments to maintain a consistent pressure that doesn't immediately peak the boss's defensive mitigation.
Crowd Control (CC) Synergy: If the boss relies on a specific "state" to maintain its life-lock, use CC-focused heroes to interrupt their attack patterns. Breaking the boss's rhythm often provides a small window of opportunity where their damage mitigation is lowered, allowing your team to land critical hits.

Managing Infinity City Progression

The difficulty of Infinity City is not linear. When you hit a floor where the enemy power scaling causes your team to struggle, use the following checklist to evaluate your status:

Factor	Strategy
Hero Level	Ensure your core DPS heroes are at the maximum level cap for your current progression tier.
Skill Timing	Save high-impact ultimate abilities for when the boss is not in a "locked" state.
Team Composition	Swap out pure-damage units for utility units if the boss's life-lock is immune to brute force.

When to Reset and Pivot

If you reach a point where your DPS has been halved (e.g., from 50s down to 20s) and you cannot break the boss’s shield or health gate despite optimal play, it is often more resource-efficient to reset the encounter or pivot your strategy rather than waiting for an auto-battle to resolve.

In Knock Knock: Room Defense, the key to Infinity City is not just having the strongest heroes, but having the flexibility to adjust your team's damage profile to counter the specific defensive gimmicks of the floor's boss. Always examine the boss's unique buffs before committing your full energy budget to a run.
