Bay Harbour Butcher — Boss Guide
The Bay Harbour Butcher is Tangy TD's most infamous boss — famous enough that the developer issued a public apology for its original difficulty, then patched it twice. Thousands of players rage-quit here before Cakez added the aggro meter and nerfed the catapult behaviour. Even after the patches, it remains the steepest wall in Story Mode. This guide explains every mechanic, every phase, and exactly what to do — so you don't have to find out the hard way.

What Changed — Patch History
The Bay Harbour Butcher shipped in a state the developer himself called "WAY TOO HARD." Understanding what changed helps you apply the right strategy — some older guides describe mechanics that no longer exist.
📋
Patch v1.0.1 — Launch Hotfix
Catapults now die when the boss dies. Previously, catapults survived the boss's death and continued firing — meaning players who killed the boss still lost because the catapults wiped their towers in the aftermath. This single change made the fight completable for most players.
📋
Patch v1.0.2 — Balance Pass
Aggro meter added. Previously, walking Tangy near the boss's patrol zone triggered an immediate pull, causing countless accidental boss engagements mid-wave. The aggro meter now fills gradually with proximity and attacks, and drains when the boss is out of sight. Boss damage reduced by approximately 15%. Spike attack wind-up time extended, giving players a larger dodge window. Enemy health on Bay Harbour waves adjusted downward slightly.
ℹ️ Guide Currency
This guide reflects the post-v1.0.2 state of the fight. If you're reading a guide that says "don't let the catapults live after the boss dies" — that was fixed in v1.0.1. Catapults now die instantly when the Butcher falls.
The Aggro Meter — The Core Mechanic
The aggro meter is the single most important mechanic in this fight. Master it and the Butcher becomes predictable. Ignore it and you'll pull the boss mid-wave every run.
The meter fills when:
- Tangy enters the boss's vision range — the largest contributor by far
- Your towers deal damage to the boss — each hit adds a small amount
- Tangy attacks the boss directly — moderate amount per hit
The meter drains slowly when the boss has no targets in sight. It does not fully drain between waves — it carries over.
Aggro Meter — Visual Reference
SAFE · No reaction
CAUTION · Boss turns toward you
DANGER · Boss pursues
PULL · Engaged
Stay out of the boss's forward vision cone during wave clearing — moving behind or to the side of the Butcher generates far less aggro
Don't attack the boss at all until your full setup is ready — each hit contributes to the meter
If the meter reaches the Danger zone mid-wave, stop all actions near the boss and let Tangy stand still until it drains back to Caution
The meter is visible as a red bar above the Butcher — check it actively, not reactively
⚠️ Most Common Death Cause
The majority of failed Butcher attempts come from accidentally pulling the boss during Wave 5 or 6 while repositioning towers. The boss enters the fight while your Defenders are damaged, your Healer is mid-cooldown, and your Archer is out of position. Always clear all waves completely and confirm your setup before approaching the boss arena.
Before You Pull — Setup Checklist
The Butcher fight is won or lost in the thirty seconds before you pull. Rush the boss with a sloppy setup and even a strong build won't save you.
1
Confirm all waves are fully cleared
Don't approach the boss arena while a straggler enemy is still alive. The distraction of clearing that last enemy while managing the boss's aggro meter has ended more runs than the boss itself.
2
Fully heal all towers
Check every tower's HP bar. Your Defender especially needs to be at or near full HP before the fight. If your Healer hasn't had time to top up the Defender post-wave, wait. The boss has no enrage timer — there's no penalty for taking 30 extra seconds.
3
Position your Defender at the chokepoint entrance to the boss arena
The Butcher arena has a natural narrow entrance. Plant your Defender here before pulling. This prevents the boss from freely walking past your entire setup during Phase 1. Do not position the Defender inside the arena — position them at the entry.
4
Position your Archer at maximum range on the backline
The Archer needs a clear line of sight to the arena entrance without being inside the boss's forward vision cone. Place them behind the Defender, angled to fire into the arena entrance. Check your Lone Ranger glow is active.
5
Place your Healer adjacent to the Defender, not between Defender and Archer
Healer coverage of the Defender is non-negotiable in this fight. The Butcher hits hard enough to drop an unhealed Defender in Phase 2. Keep the Healer within aura range of the Defender at all times.
6
Use the Cauldron if you have any dead item slots
A Common stat item in any slot is a wasted opportunity before the hardest fight in Story Mode. Cauldron it for a chance at something with an ability. You have time — the boss waits.
7
Pull deliberately — approach slowly from the side
Walk Tangy toward the boss arena from the side, not head-on. The Butcher's forward vision cone is narrower than its side vision. A slow side approach fills the aggro meter gradually, letting you stop and reverse if you overshoot. Never sprint directly at the boss.
Phase-by-Phase Breakdown
The Butcher has three distinct phases, each introducing a new attack and escalating the aggression of existing ones. Knowing when a new phase triggers lets you reposition proactively rather than reactively.
The Butcher moves deliberately in Phase 1. Its attacks are telegraphed and avoidable. This is your window to deal damage safely before the fight escalates.
Heavy Swing MODERATE
A slow melee arc in front of the boss. 1.5-second wind-up with a visible arm raise animation. Move any tower out of the frontal arc — the hitbox is wide but shallow. Your Defender can tank this repeatedly if the Healer is active.
Ground Stomp MODERATE
Slams the ground, creating a shockwave in a small radius. Short wind-up. Does not chase targets — stay at medium range and you won't be hit. Mainly affects towers that are too close to the boss during melee range.
✓ Phase 1 Goal
Use this phase to deal as much damage as possible before the catapults spawn. Keep your Defender absorbing the melee attacks, your Healer running, and your Archer dealing full DPS from the backline. The faster you push the boss to 65% HP, the less time the catapults have to become a problem.
At 65% HP, the Butcher calls in catapults that spawn on the harbour's elevated platforms. These siege weapons fire at your tower positions every few seconds and represent the most complex threat management in the fight.
Heavy Swing MODERATE
Same as Phase 1 but slightly faster. Wind-up reduced to ~1 second. Keep the Defender in position and continue tanking.
Catapult Barrage HIGH
Two catapults on elevated platforms fire projectiles at your tower positions. Each shot deals significant damage to whichever tower occupies that position. The projectiles have a visible arc — you can see them incoming. Key: the catapults target the position, not the tower. Moving a tower out of position before the shot lands prevents all damage.
Charge HIGH
New in Phase 2. The Butcher winds up and rushes forward in a straight line. Any tower in the charge path takes heavy damage. The charge line is telegraphed by a brief ground scrape animation. Move towers perpendicular to the Butcher's facing direction immediately — the charge is fast once it starts.
⚠️ Priority in Phase 2
Focus on the Butcher, not the catapults. The catapults die automatically when the boss dies — your time is better spent burning the boss HP from 65% to 30% than repositioning towers away from catapult fire. Use Tangy to move your most vulnerable towers (Archer, Healer) out of catapult target zones when you see shots incoming, but don't stop your DPS towers from attacking the boss.
At 30% HP, the Butcher enrages. Movement speed increases noticeably. Most critically, the Spike Attack is introduced — the one that got the boss patched twice after it was one-shotting entire setups on launch day.
Heavy Swing HIGH
Wind-up reduced further. Damage increased. Your Defender needs consistent Healer coverage to survive through Phase 3. If your Defender falls here, the fight is almost certainly over.
Catapult Barrage HIGH
Catapults continue firing. In Phase 3, their fire rate increases. Continue the Phase 2 strategy: reposition your Archer and Healer away from incoming shots while keeping your Defender in melee range of the boss.
Spike Attack LETHAL
The Butcher slams the ground, sending spikes radiating outward in a fixed cross or star pattern. Any tower hit by a spike takes massive damage — enough to one-shot a fully-HP Archer or Healer. The wind-up is a loud audio cue followed by the boss crouching low. You have approximately 1.5 seconds to move any non-Defender towers out of the spike pattern. The pattern is always consistent — spikes travel along the cardinal directions from the boss's position. Stay diagonal to the boss to be safe from all spikes simultaneously.
Rapid Charge HIGH
The charge from Phase 2 now triggers more frequently and covers more distance. The wind-up animation is shorter. Prioritise having your Archer and Healer offset from the boss's facing line at all times.
⚠️ The Spike Survival Rule
As soon as the Butcher's health drops below 30%, stop placing any tower directly in a cardinal direction from the boss. Position your Archer and Healer on the diagonals — northeast, northwest, southeast, or southwest of the boss's position. The spikes cannot hit a diagonal position. Your Defender continues tanking frontally because they can survive a spike hit; your Archer and Healer cannot.
Managing the Catapults
🏹 Catapult Mechanics — Key Facts
- Catapults target tower positions, not the towers themselves. Picking up a tower and placing it elsewhere before the shot lands avoids all damage.
- Catapults die when the boss dies. (Post-v1.0.1 — do not attempt to attack catapults during the fight.)
- Two catapults spawn at 65% boss HP on the harbour's elevated flanks.
- Catapult fire rate increases in Phase 3 (below 30% boss HP). This is when catapult pressure is highest — simultaneously managing spike dodging and catapult repositioning is the hardest skill check in the fight.
- Your Defender can tank catapult shots without dying if your Healer is active. Only reposition the Defender if your Healer is dead or out of range.
The correct catapult management strategy is counterintuitive: don't focus the catapults, focus the boss.
Before the patch, catapults survived the boss's death and continued firing — so killing them was necessary. Now, every second you spend running Tangy toward a catapult position is a second your Archer isn't dealing damage to the boss. A run that kills the boss in 90 seconds with catapults up is better than a run that kills two catapults in 45 seconds and then dies to Phase 3 with the boss at 40% HP.
The one exception: if a catapult shot is going to hit your Archer or Healer and they're already low on HP, pick them up and move them. A repositioned Archer loses a second of DPS. A dead Archer loses the rest of the fight.
Recommended Builds for This Fight
The Butcher is a hybrid fight — you need wave-clearing capability for the pre-boss waves and strong single-target damage for the boss itself. The builds below are optimised for the full Bay Harbour map, not just the boss.

👟S4Speed Boots
Speed Boots on the Healer is particularly important in this fight. Phase 2 and Phase 3 require constant tower repositioning in response to catapult shots and spike patterns. A faster Healer maintains aura coverage on the Defender through all of that movement, where a slow Healer gets left behind as you reposition.
Ivy Bow's root on the Bleed Stack Archer is extremely valuable against the Butcher — a 0.8-second root on a boss that charges and swings constantly is a huge DPS window. The root can trigger once every 4 seconds per target, which means roughly every other attack cycle in Phase 1 and Phase 2 at standard attack speed.
5 Mistakes That Kill Every Run
1
Pulling the boss before Wave 6 is fully cleared
The most common death by far. Walking Tangy toward the boss arena to scout positions while one or two enemies are still alive is how most players accidentally trigger the fight in a compromised state. Wait. Clear everything. Then approach.
2
Placing towers in cardinal lines from the boss during Phase 3
The Spike Attack travels north, south, east, and west from the boss's position. Any tower in a cardinal direction takes lethal damage. The solution is simple but requires remembering it under pressure: diagonals are always safe. Reposition your Archer and Healer to diagonal positions the moment the boss hits 30% HP — not after you see the spike wind-up animation.
3
Wasting time attacking catapults
Pre-patch behaviour. Catapults die when the boss dies now. Every second you spend attacking the elevated platforms is a second the boss doesn't die. Focus all DPS on the Butcher.
4
Moving the Defender away from the chokepoint during Phase 2
Catapult shots can make players panic and move their Defender out of position — especially if the Defender is taking catapult hits. Don't. The Defender at the chokepoint is what prevents the Butcher from freely walking into your Archer and Healer. Heal through catapult damage. Only move the Defender if it's at critical HP with no Healer coverage, and even then, pick it up and replant it at the chokepoint, not somewhere else.
5
Cancelling the Archer's Lone Ranger bonus during the fight
Panic repositioning under catapult fire frequently ends with towers clustered together. Every time your Archer loses the Lone Ranger +20% bonus, your DPS drops — and DPS is the only way this fight ends. When repositioning, always move your Archer and Healer in opposite directions: Archer further back, Healer toward the Defender. Never cluster.
✓ One Final Tip
There is no timer on this fight. The Butcher does not enrage based on time — only based on HP thresholds. If your run is going badly in Phase 2, stop dealing damage and let your Healer top up every tower before resuming. You can pause the fight's escalation by simply not hurting the boss. Use that window.
Next Boss
Once you've cleared Bay Harbour, the Mountain Trail map opens. The Mountain Trail boss — The Warden — has a patrol pattern that requires different aggro management. See the
