The House TD 2 floor 4 guide: Room 5 Setup
The House TD 2 floor 4 guide is centered on Room 5, the final encounter of Floor 4. The most reliable plan is not tied to one exact roster. Instead, build a defense with crowd control, sustained lane coverage, and focused boss damage.
The encounter rewards careful placement more than constant unit replacement. Start by covering the opening route with AoE units, then strengthen the middle and rear of the map with beam units and long-range attackers. Save enough resources to react when the main boss appears on wave 21.
Video Highlights:
- Uses AoE units near the opening route for early crowd control
- Places additional damage dealers near T-junctions and crossing lanes
- Switches single-target units to the strongest target
- Slows the game before the wave 21 boss reaches close range
- Repositions units according to the boss’s path
Treat every corner, cross, and T-junction as a damage opportunity. Units placed there can attack enemies during more of their route.
Recommended Unit Roles
A balanced lineup should include the following roles:
- AoE units: Clear groups and soften enemies before they reach the back line.
- Beam units: Apply consistent damage through longer portions of the route.
- Single-target units: Focus elite enemies and bosses with the strongest targeting mode.
- Flexible damage units: Fill gaps after the main route becomes clear or the boss changes direction.
The strategy shown with Crimson Duchess, Demon Princesses, Cats, Seeker, and Torments is an example rather than a mandatory roster. Similar units can work if they provide the same functions.
| Unit Role | Main Job | Preferred Location | Upgrade Priority |
|---|---|---|---|
| AoE | Crowd control and group damage | Start, corners, T-junctions | High |
| Beam | Sustained lane coverage | Center to rear | High |
| Single-target | Elite and boss damage | Central or extended-range spots | High |
| Flexible damage | Cover weak routes | Open lanes and side choke points | Medium |
| Support or reserve | Emergency response | Kept available for wave 21 | Situational |
Opening Waves and Economy Management
The opening waves should establish your defensive shape without spending every resource immediately. Place one or two AoE units near the beginning of the route, where grouped enemies can remain inside their attack range for as long as possible.
After the first wave of enemies is controlled, add coverage at the map’s smaller choke points. A T-junction is especially valuable because enemies may remain exposed to the same unit while turning or changing lanes.
The recommended upgrade order is:
- Improve the first AoE unit enough to handle early groups.
- Add a second AoE unit at another high-traffic intersection.
- Upgrade the strongest central damage dealer.
- Add beam coverage toward the middle or rear.
- Prepare single-target units before elite enemies become difficult to stop.
Avoid placing every expensive unit at the front. Front-loaded defenses may clear the first enemies quickly but leave too little damage near the end of the route. A layered defense gives you more opportunities to defeat enemies before they reach the exit.
Front AoE
Controls early groups and prevents small enemies from overwhelming the first lane.
Intersection AoE
Uses turns and crossings to increase the number of attacks against passing enemies.
Central Beam
Provides sustained damage across a long section of the route.
Boss Targeter
Focuses the strongest enemy after switching its targeting mode to Strongest.
Use speed controls during safe waves if desired, but return to a slower speed when elites or the boss enter close range. This gives you time to sell, move, or upgrade units.
Suggested Progression
| Stage | Primary Action | Reason |
|---|---|---|
| Early waves | Place opening AoE | Stabilizes grouped enemies |
| First upgrades | Strengthen front and intersection coverage | Improves income and wave control |
| Mid waves | Add beam and single-target damage | Prepares for tougher enemies |
| Before wave 21 | Save resources and inspect the route | Allows emergency repositioning |
| Boss wave | Rebuild around the boss path | Concentrates damage where it matters |
Step-by-Step Floor 4 Room 5 Walkthrough
Use this four-stage process to keep the defense organized from the first wave through the Shadow Court encounter.
Secure the Opening Route
Place your first AoE unit near the beginning of the path. Add another AoE unit near the first corner, cross, or T-junction. These placements should handle grouped enemies before they spread across the map.
Build the Middle Defense
Add your strongest sustained damage units in central positions. Beam units generally benefit from the center-to-rear area, while long-range units can cover several sections without competing for the same front placement.
Add Focused Damage
Place Seeker-type or other single-target units where they can attack elite enemies for multiple seconds. Change their targeting priority to Strongest so they do not waste attacks on weaker enemies while a dangerous target advances.
React to Wave 21
Slow the game when the main boss appears. Watch the route, sell units that lose access to the boss, and rebuild them at the next useful corner or lane. Upgrade the replacement units immediately when possible.
The boss may travel around the field rather than follow the route you expect at first. Do not commit to a full rearrangement until the direction is clear. A small number of well-timed sales and replacements can create a stronger firing line without dismantling the entire defense.
| Walkthrough Moment | What to Watch | Correct Response |
|---|---|---|
| Opening groups | Enemies stack together | Keep AoE near the first route |
| Mid-wave elites | Strong enemies survive the front line | Add beam or focused damage |
| Boss entrance | Boss direction and current health | Pause or slow the game |
| Boss turn | Existing units lose range | Reposition toward the next lane |
| Final approach | Boss reaches the back half | Concentrate upgrades and strongest targeting |
Selling units too early can remove important coverage from other enemies. Confirm the boss route first, then move only the towers that no longer contribute meaningful damage.
Boss Control, Equipment, and Targeting
The Floor 4 Room 5 boss is the main test of your formation. The strategy works best when the boss is attacked by several damage types at once: AoE for nearby enemies, beams for sustained pressure, and single-target units for concentrated damage.
The Angry Oni enemies can also create pressure before the final boss. Keep the strongest units upgraded instead of spreading resources evenly across every tower. A partially upgraded back line may be less valuable than a fully upgraded central damage dealer that attacks elites and the boss repeatedly.
Targeting Priorities
Use these targeting rules as a baseline:
- Set single-target units to Strongest when elite enemies or bosses are present.
- Keep AoE units in positions where they can hit multiple enemies.
- Place beam units toward the center or rear when their range reaches long stretches of the route.
- Avoid moving units simply because a new placement looks attractive; compare the number of attacks they gain or lose.
- Recheck targeting after selling and replacing units.
Equipment Recommendations
The available strategy emphasizes equipping damage dealers with armor and using Devil’s Pact on AoE units. Nightmare may be more difficult to obtain, so Devil’s Pact is a practical benchmark when preparing for this room.
| Equipment Focus | Best Users | Purpose | Priority |
|---|---|---|---|
| Armor | Main damage units | Improves the readiness of equipped units | High |
| Devil’s Pact | AoE units | Supports stronger crowd-control performance | High |
| Higher-tier damage gear | Boss and elite attackers | Improves focused damage potential | Medium to high |
| Flexible equipment | Units filling multiple roles | Keeps the roster useful if placements change | Medium |
Before wave 21, make sure at least one group of units can focus the strongest enemy while your AoE and beam units continue controlling surrounding enemies.
When to Reposition
Repositioning is most valuable when:
- The boss leaves an important attack range.
- A unit is trapped on a short lane with few targets.
- A corner or cross provides more attack time.
- The back line lacks enough damage to finish the boss.
- A temporary unit can be sold for an immediate, high-value upgrade.
Do not treat selling as failure. In this room, controlled repositioning is part of the strategy. The goal is to keep your strongest attacks active against the boss for as much of its route as possible.
Preparation Checklist and Common Mistakes
Before entering Room 5, verify that your lineup has the tools needed for both groups and bosses. A roster containing only one damage style may perform well during the opening waves but struggle when enemy health rises.
Room 5 Preparation:
- Bring reliable AoE coverage for opening groups and intersections
- Include beam or long-range units for sustained middle and rear damage
- Prepare at least one single-target option for elite enemies and bosses
- Equip armor and consider Devil's Pact for important damage units
- Reserve enough resources to reposition during wave 21
Common Errors to Avoid
| Mistake | Why It Causes Problems | Better Adjustment |
|---|---|---|
| Placing every AoE unit at the start | Later enemies receive little damage | Spread AoE across intersections |
| Ignoring the center of the map | Beam and range value is reduced | Use central positions for sustained attacks |
| Leaving single-target units on First | They may attack weak enemies | Switch to Strongest for elites and bosses |
| Upgrading every unit equally | Core damage remains too low | Max key central and boss units first |
| Rebuilding before seeing the boss route | Resources are spent inefficiently | Wait for the boss direction |
| Running maximum speed during danger | Reactions become harder | Slow down near elites and wave 21 |
A strong formation has an opening layer, a central damage layer, and a final boss-control layer. If one layer fails, the next one still has time to respond.
The most common placement error is confusing a visually convenient location with a high-value location. Prioritize the number of route segments a unit can attack, the density of enemies in that area, and whether the unit can reach the boss after wave 21 begins.
A second mistake is overcommitting to one named unit. Crimson Duchess, Demon Princesses, Seeker, Cats, and Torments can form a useful example composition, but the underlying roles matter more than the exact names. Substitute units should still provide AoE, beam coverage, focused damage, or flexible range.
Q: What is the best team structure for The House TD 2 floor 4 guide?
Use a mix of AoE units for grouped enemies, beam units for sustained lane damage, and single-target units for elite enemies and the Room 5 boss. The exact roster can vary as long as those roles are covered.
Q: Where should I place AoE units in Floor 4 Room 5?
Prioritize the start of the route, corners, crosses, and T-junctions. These locations usually provide repeated attack opportunities against grouped enemies and turning lanes.
Q: What should I do when the wave 21 boss appears?
Slow the game, identify the boss direction, and reposition units that lose range. Set focused attackers to Strongest, then upgrade the units that can attack the boss for the longest portion of its route.
Q: Do I need the exact units used in this guide?
No. The named units are examples of useful roles. Comparable AoE, beam, and single-target units can work when placed at strong intersections and supported with suitable equipment.
