Finding the Broodmother's Lair
The Broodmother hides in a secret chamber in the northwest section of The Slab. Her location is revealed through environmental storytelling and quest mechanics.
Navigation Tips
- Starting Point: Enter The Slab from Choral Chambers or use the Grand Bellway

- Secret Entrance: Look for an interactable crack in the wall once the quest is active
- Linear Path: Once inside, the path to the boss chamber is straightforward
Remember: The slime trails serve as both a tracking mechanism and environmental storytelling, showing the Broodmother's influence throughout The Slab.
Recommended Equipment & Strategy
The Broodmother fight heavily favors area-of-effect damage and spawn management. Your loadout should prioritize tools that can handle multiple targets while maintaining consistent damage output.
Primary Tools (Essential)
- Voltvessels: Main damage source, excellent for slow targets
- Cogfly: Increases damage uptime, perfect for spawn clearing
- Pollip Pouch: Adds poison to Cogfly for faster minion kills
Support Tools (Helpful)
- Druid's Eye: Passive Soul building for sustainability
- Memory Crystal: Damage on taking hits (alternative)
- Magnetite Dice: Chance to negate damage
Crest Recommendations
Reaper Crest (Recommended)
Wide pogo jumps and slashes provide excellent reach for both boss and spawn management. The extended range is crucial in this fight.
Witch Crest (Alternative)
Fast movement and ability to equip 3 Blue Tools. However, lacks yellow slot for Magnetite Dice.
Architect Crest (Aggressive)
Replaces Silk Skill with extra Red Tool. Allows crafting mid-fight for extended aggression.
Core Strategy Principles
- 1. Reach is King: Prioritize tools and attacks with wide area coverage
- 2. Spawn Priority: Always eliminate flying spawns before focusing on the boss
- 3. Aerial Advantage: Stay airborne when possible - most attacks target ground level
- 4. Tool Management: Charge tools at the nearby bench before entering the arena
- 5. Patience Pays: The boss is slow - don't rush into dangerous situations
Pre-Boss Enemy Waves
Before facing the Broodmother directly, Hornet must survive three increasingly difficult waves of flying enemies. These serve as both a warm-up and a tool charge opportunity.
Wave 1: Basic Spawn Training
Enemies: 4x Freshflies
Strategy: Hit each fly once to kill them. 1-2 Cogflies should easily clear this wave.
Focus: Get comfortable with spawn timing and explosion ranges.
Wave 2: Mixed Threats
Enemies: 3x Freshflies + 1x Guardfly
Strategy: Quickly eliminate the Guardfly before Freshflies start bouncing off walls.
Focus: Priority targeting and area control.
Wave 3: Elite Challenge
Enemies: 3x Freshflies + 1x Wardenfly
Strategy: Deal with Freshflies first since the Wardenfly moves slowly.
Focus: Managing multiple threats while avoiding the Wardenfly's powerful attacks.
Wave Management Tip: Use these waves to practice your spawn-clearing techniques and charge your tools. The skills you develop here directly translate to success against the Broodmother herself.
Phase 1: Basic Combat Pattern (700-385 HP)
In the first phase, the Broodmother hovers around the upper half of the arena and employs four distinct attack patterns. Understanding and countering each is essential for a clean victory.
Broodspawn Attack
Pattern: Broodmother spawns 1-2 Freshflies diagonally below her position.
Counter Strategy: Immediately prioritize killing these spawns - they don't despawn and will create chaos if ignored. Use Cogfly or Voltvessels for quick elimination. Stay mobile to avoid their explosion damage.
Key Point: The explosion damage doesn't hurt the Broodmother, so position spawns between you and her when possible.
Muck Spit Attack
Pattern: Broodmother spits 1-2 globs of sticky muck diagonally downward toward Hornet.
Counter Strategy: Watch for the telegraph (tilting head back) and jump or dash away. The muck always aims low, so aerial positioning is safe. If caught, press ATTACK 4 times rapidly to break free.
Key Point: Muck globs can be destroyed by attacking them, but it's usually better to simply avoid the area.
Grabbing Leap Attack
Pattern: Broodmother rears back, then launches herself across roughly half the arena. Can chain up to 3 times if Hornet remains in range.
Counter Strategy: This is your main damage opportunity. Position yourself for pogo strikes when she lands. Stay in the middle of the arena to potentially get 3 successive pogo hits. Avoid being directly above her after the final leap.
Key Point: She flies directly upward after the attack sequence, so don't be above her at that moment.
Buzz Away
Pattern: Broodmother flies backward a short distance if Hornet gets too close.
Counter Strategy: This is a defensive move that gives you space. Use this time to clear any remaining spawns or reposition for her next attack.
Key Point: This move signals that you were applying good pressure - continue being aggressive but with proper spacing.
Phase 1 Optimal Strategy
- 1. Spawn Control: Always eliminate Freshflies immediately - they're your biggest threat
- 2. Aerial Positioning: Stay airborne to avoid Muck Spit and maintain mobility
- 3. Pogo Opportunities: Use Grabbing Leap as your primary damage window
- 4. Tool Usage: Deploy Voltvessels and Cogfly when the boss is stationary
- 5. Corner Safety: Position in arena corners to bait predictable Grabbing Leap patterns
Phase 2: Wild Slam Fury (385-0 HP)
At 385 HP, the Broodmother becomes more aggressive, immediately performing Wild Slam and adding it to her regular attack rotation. This phase requires precise timing and positioning.
Wild Slam Attack - Detailed Breakdown
Pattern: Broodmother wails, then slams between floor and ceiling 5 times, moving forward with each slam and turning at walls without stopping.
Slam Sequence
- • Always starts with downward slam
- • Alternates floor → ceiling → floor → ceiling → floor
- • Moves forward slightly with each impact
- • Turns instantly when hitting walls
- • Always ends with ground slam
Counter Strategy
- • Positioning: Stay as close as possible when she begins the wail
- • First Dodge: Dash under her as soon as she rushes upward for the first slam
- • Wall Avoidance: Never position near walls - unpredictable bouncing occurs
- • Follow Through: Once under her, continue moving in the same direction
- • End Position: Be ready for normal attacks after the final ground slam
Phase 2 Combat Flow
The Broodmother retains all Phase 1 attacks while adding Wild Slam. Her pattern becomes less predictable, requiring adaptation to mixed attack sequences.
Advanced Positioning Strategy
- 1. Center Control: Maintain central positioning to avoid wall complications during Wild Slam
- 2. Audio Cues: Listen for the distinctive wail that signals Wild Slam initiation
- 3. Dash Timing: Wait for upward movement before dashing - don't predict too early
- 4. Recovery Position: After dodging Wild Slam, immediately clear any spawns she created earlier
- 5. Damage Windows: The end of Wild Slam provides a brief opening for tool deployment
Common Mistakes & Solutions
Many players struggle with specific aspects of the Broodmother fight. Here are the most frequent mistakes and how to avoid them.
Mistake: Ignoring Spawns
Problem: Focusing on the boss while Freshflies accumulate and create chaos.
Solution: Always prioritize spawn elimination. A room full of Freshflies is more dangerous than the boss herself.
Mistake: Getting Stuck in Muck
Problem: Standing still when Broodmother aims Muck Spit, leading to immobilization and follow-up damage.
Solution: Maintain constant movement. Jump immediately when you see her tilting her head back.
Mistake: Poor Wild Slam Positioning
Problem: Standing too far away or near walls when Wild Slam begins, making dodging difficult.
Solution: Stay close to her and in the center of the arena. Dash under her the moment she rises.
Mistake: Wasting Tools Too Early
Problem: Using all charged tools in Phase 1, leaving nothing for the more difficult Phase 2.
Solution: Save at least half your tools for Phase 2. Use basic attacks and pogo strikes efficiently in Phase 1.
Advanced Techniques & Pro Tips
Master these advanced strategies to trivialize the Broodmother encounter and ensure consistent victories.
Spawn Explosion Manipulation
Position yourself so that when you kill Freshflies, their explosions damage the Broodmother. Since her own spawns' explosions don't hurt her, timing is crucial.
Technique: Kill spawns when they're between you and the boss for free extra damage.
Perfect Pogo Chains
During Grabbing Leap sequences, position in the exact center of the arena to potentially land three consecutive pogo strikes as she chains her leaps.
Timing: Jump and attack just as she touches the ground, then immediately prepare for the next leap.
Tool Synergy Combinations
Combine Voltvessels with Cogfly deployment for maximum area coverage. Deploy Cogfly first to draw spawns, then Voltvessels to hit both spawns and boss.
Optimal Sequence: Cogfly → wait 1 second → Voltvessels → maintain pressure with pogo strikes.
Phase Transition Optimization
When the boss reaches 385 HP, she immediately performs Wild Slam. Clear all spawns before bringing her to this threshold to avoid dealing with both mechanics simultaneously.
Strategy: Stop attacking at ~400 HP, clear all spawns, then trigger Phase 2 with a clean arena.

Troubleshooting & Common Issues
Encountering problems with the Broodmother fight? These solutions address the most frequent technical and strategic issues.
Problem: Can't Find the Boss Chamber
Symptoms: No visible entrance despite having the quest active.
Solutions: Ensure The Wailing Mother quest is properly accepted from Songclave Wishwall. The entrance only appears after quest activation. Look for a subtle crack in the northwest wall of The Slab.
Problem: Overwhelmed by Spawns
Symptoms: Arena fills with too many Freshflies to manage effectively.
Solutions: Prioritize spawn clearing over boss damage. Use area-of-effect tools exclusively until spawns are eliminated. Consider respeccing to Witch Crest for multiple Blue Tools.
Problem: Consistently Dying to Wild Slam
Symptoms: Unable to avoid the Phase 2 Wild Slam attack pattern.
Solutions: Practice the timing in Phase 1 by staying close to her during other attacks. The key is being close when she starts the wail, then dashing under her immediate upward movement.
Problem: Running Out of Tools
Symptoms: All tools depleted before boss is defeated.
Solutions: Use the nearby bench to recharge before entering. Consider Architect Crest for mid-fight crafting. Focus on pogo damage and only use tools for spawn clearing and guaranteed hits.
