Knock Knock: Room Defense – How to Optimize Hero Deployments for the Ghost Festival Event

The Ghost Festival event introduces unique combat challenges that require a shift in your standard defensive rotation. To maximize your efficiency during these limited-time encounters, you must prioritize specific hero synergies and resource allocation. This guide breaks down the essential tactics for navigating the Ghost Festival event stages effectively.

Core Strategies for Ghost Festival Success

During this event, the enemy density and spawn rates differ significantly from standard campaign stages. Players who rely on brute force often fail; instead, focus on these three pillars:

Crowd Control (CC) Priority: Because the event features waves of ghosts with varying movement speeds, your primary goal is to stall the frontline. Ensure your team includes at least two heroes with reliable knock-back or stun capabilities to keep the room entrance clear.
Energy Efficiency: Don't waste your initial gold reserves on low-tier upgrades. Focus on scaling your core DPS hero first to ensure you can clear the early waves without falling behind on the economy.
Positional Synergy: The Ghost Festival maps often feature restrictive layouts. Place your highest-damage heroes in "dead zones" where they can hit multiple lanes, and keep your sustain/tank heroes near the door to maximize the uptime of their defensive buffs.

Recommended Hero Archetypes

When building your roster for the event, prioritize heroes that perform well under high pressure.

Hero Role	Priority	Function in Event
Crowd Control	High	Pushes enemies back to allow for sustained DPS.
Single-Target DPS	High	Essential for burning down elite ghosts quickly.
Support/Buff	Medium	Increases attack speed or damage output for the team.
AOE Damage	Low	Only useful if your team lacks single-target boss-killers.

Tactical Execution Tips

Monitor Your Gold Economy: The Ghost Festival event rewards players who can balance upgrading their room defenses with hero deployments. If you find your gold production lagging, prioritize the "Passive Income" upgrade path early in the match.
Adaptive Hero Swapping: If a wave contains high-health enemies, swap your AOE heroes for specialized single-target burst characters. Flexibility is the key to surviving the later stages of the event.
Manage Your Cooldowns: Do not use all your hero abilities at the start of a wave. Save your high-impact skills for when the ghosts congregate near the door. This ensures you have a safety net if your primary defense is breached.

Avoiding Common Pitfalls

Over-extending: Do not spread your heroes out too thin. It is better to have one heavily upgraded defensive line than three weak ones that can be easily overwhelmed.
Ignoring Synergy: Even if a hero has a higher power rating, they may not fit the team composition. Always prioritize heroes that offer crowd control if you are struggling to keep the ghosts away from your door.
Panic Upgrading: Avoid upgrading random room features. Focus strictly on the door health and your primary defensive turret/hero slots to ensure you don't run out of gold during critical mid-game waves.

By focusing on crowd control and maintaining a disciplined economy, you can consistently clear the higher tiers of the Ghost Festival event. Focus on testing different hero combinations to see which team composition best suits your current power level and playstyle.
