Gaming Guides

Have you been grinding through Forsaken matches, desperately trying to unlock the most intimidating John Doe skin in the game? I’ve spent countless hours mastering both Forsaken and The Battle Bricks to bring you this complete, step-by-step guide to obtaining the legendary Treachstone John Doe skin. This isn’t just another basic tutorial – I’m going to walk you through every single requirement, strategy, and secret to unlocking this coveted collab skin that has the entire Roblox horror community talking.

The Treachstone John Doe skin represents one of the most challenging crossover rewards in Forsaken’s history, requiring you to conquer The Battle Bricks’ brutal TUMORE difficulty mode. Unlike simple shop purchases, this exclusive skin demands real skill, strategic planning, and dedication across multiple game modes. Whether you’re a Forsaken veteran curious about this frozen terror or a Battle Bricks player ready to show off your achievements, this comprehensive guide covers everything you need to know in March 2026.

What is Treachstone John Doe?

Treachstone John Doe is an exclusive collab skin that transforms John Doe into Treachstone, the final boss of The Battle Bricks’ Frozen Legion subchapter that appears exclusively in TUMORE difficulty mode. This menacing character features dark clothing with a black hood concealing glowing eyes, a luminous blue cross on his torso, black horns, spikes on his shoulders and back, stone gauntlets with his right arm frozen over, icy wings, and ice blocks covering parts of his body.

Understanding TUMORE Mode in The Battle Bricks

Before you can even think about unlocking Treachstone John Doe, you absolutely must understand what TUMORE mode is and why it’s considered The Battle Bricks’ ultimate challenge.

What Makes TUMORE Mode So Challenging?

TUMORE is The Battle Bricks’ hardest difficulty where enemies shift into alternate forms and stage magnifications with base HP are significantly increased, demanding tighter summon cycles and stronger unit investment than Normal mode. Let me break down exactly what this means for your gameplay:

TUMORE Difficulty Changes:

Enemy Transformations: All enemies convert into their terrifying alternate forms
Doubled Magnification: Every stage’s magnification values are doubled
+100% Base HP: Enemy health pools increase by 100%
Higher DPS Requirements: You need significantly better damage output
Sustain Challenges: Your units must survive longer against enhanced threats

How to Unlock TUMORE Mode?

From The Battle Bricks title screen, repeatedly click or tap the tumor logo on startup to reveal and enable TUMORE mode if it’s not visible. This is the most common access method that many new players miss.

Step-by-Step TUMORE Unlock:

Launch The Battle Bricks on Roblox
Wait for the main title screen to load completely
Look for the “tumor” logo on the startup screen
Repeatedly click/tap the tumor logo until the difficulty toggle appears
Once unlocked, you can switch between Casual, Normal, and TUMORE difficulties

Pro Tip: Don’t attempt TUMORE mode immediately after unlocking it. Build a strong roster first through Normal mode progression!

Treachstone John Doe Requirements: What You Actually Need?

This is where things get complicated, and I’m going to give you the complete truth about what’s required. The community has shared conflicting information, so let me clarify the actual requirements based on current in-game data.

Official Requirements (Verify In Your Collab Tracker)

Treachstone John Doe is documented as achievable via the “Chapter 4 – Utopia” badge, though community threads also note requirements for Chapter 3 TUMORE (≥1 star) plus Chapter 4 Normal (≥1 star).

Requirement Variations:

Version 1: Complete Chapter 4 and earn the “Utopia” badge only
Version 2: Complete Chapter 3 TUMORE (1+ stars) AND Chapter 4 Normal (1+ stars)

How to Verify Your Requirements?

CRITICAL: Always check your in-game collab tracker! Here’s how:

Open Forsaken on Roblox
Navigate to the Collab Menu
Find The Battle Bricks collab section
Check your specific badge requirements listed
Open The Battle Bricks
Check the collab panel for Battle Bricks-side requirements

Different regions or game versions may have slightly different requirements, so never rely solely on external guides (including this one) without verifying in your actual game client.

Complete Beginner-to-Expert Roadmap

Now that you understand the requirements, let me give you my proven zero-to-hero progression plan that will get you to Treachstone John Doe as efficiently as possible.

Phase 1: Normal Mode Foundation (Days 1-7)

Finish Chapter 1 on 3 stars in Normal first to stabilize EXP and unlock an additional unit, giving a stronger springboard for TUMORE routing. Don’t skip this step – it’s absolutely essential.

Chapter 1 Strategy:

Complete all 30 stages on Normal difficulty
Aim for 3-star completion on every stage
Farm EXP consistently to level your starter units
Unlock the additional unit slot (game-changing)
Learn basic tower defense mechanics thoroughly

Essential Units to Focus On:

Prioritize Sword over other starters for reliable DPS
Build up Trowel for defensive capabilities
Don’t neglect cheap meatshield units (they’re crucial later)

Aim for Chapter 2 three-star Normal before deep TUMORE pushes; the Chapter 2 badge unit’s alt form is cited as very helpful for Chapter 3 TUMORE fights.

Phase 2: TUMORE Introduction (Days 8-14)

Once you’ve mastered Normal mode for Chapters 1 and 2, it’s time to dip your toes into TUMORE difficulty.

Your First TUMORE Attempts:

Start with Chapter 1 TUMORE (easier than you think with good Normal rosters)
Focus on consistent meatshield uptime
Let your carry units ramp up damage safely
Don’t worry about 3-stars yet – just clear stages

Chapter 2 TUMORE will punish low levels and weak cycling; use your best stallers and consider pausing star attempts until more EXP can be banked from Normal clears.

Phase 3: The Chapter 3 TUMORE Grind (Days 15-30)

Chapter 3 TUMORE is a common collab bottleneck; treat 1-star as the primary milestone for forsaken requirements when both Chapter 3 TUMORE and Chapter 4 Normal are listed in your panel.

This is where 90% of players get stuck, so pay close attention to my strategies:

Core Team Building for Chapter 3 TUMORE:

Stack cheap meatshields (Tumored Battler, Blonde Battler, Builder Battler)
Include mid-cost DPS anchors (Newell Battler, Mage Battler)
Add late-game boss shredders (Trebuchet, Lil’ X-TREME)
Don’t forget support units (Healorb Battler for sustain)

TUMORE Loadout Principles:

Expect massive health and damage spikes from doubled magnifications
Deploy meatshields continuously to stall enemy advances
Position DPS units behind meatshield walls
Save money for power spikes when bosses appear

Phase 4: Chapter 4 Normal Completion (Concurrent with Phase 3)

If your requirements include Chapter 4 Normal, work on this simultaneously with Chapter 3 TUMORE practice.

Chapter 4 Strategies:

Apply everything you learned from earlier chapters
Use your best-leveled units
Focus on 1-star completion first, optimize later
Farm additional stages if you need more EXP or Bricks

Understanding Treachstone: The Boss You Need to Beat

To truly master the requirements, you need to understand Treachstone himself – the terrifying boss that inspired this John Doe skin.

Treachstone’s Lore and Design

Treachstone is the alternate form of Bedridden, remaining stationary until damaged or when the cannon is used, with far higher damage output and damage over time plus backline killing capabilities, in exchange for moving slower and having much less resistance.

Treachstone’s Name Origin:

Portmanteau of “treacherous” and “stone”
References Dante’s Inferno’s 9th circle of Hell (Treachery)
The frozen wasteland theme reflects sinners frozen for betrayal

Visual Design Elements:

Monster Face with glowing eyes
Scary Hood (recolored dark blue)
Frozen Horns (recolored pitch black)
Dark Spike Chain (recolored black)
Black and Red Cross (neon material, deep blue)
Shadow Lord’s Spikes (both shoulders)
Booster Gloves and Frost Mantle (both recolored black)

Treachstone’s Battle Phases

Understanding how Treachstone fights helps you appreciate why this skin is so prestigious:

Phase 1: The Sleeping Giant

Remains stationary at base for 15 seconds
Only awakens if damaged or if cannon is used
Players must build up massive DPS before awakening him
Lightning strikes when awakened, followed by 4-second laugh animation

Phase 2: The Frozen Fury (Below 50% HP)

Falls and freezes over, sprouting giant wings
Begins flying with increased movement speed
Resistance drops from 60 to 30
Attack speed increases dramatically
Every attack now produces 3 devastating shockwaves

Upon dying, he will fall to the ground again crushing any units under him and will freeze over entirely, reaching up to the sky for one last time before finally dying. It’s one of the most epic boss death animations in The Battle Bricks!

Advanced Strategies: How the Pros Complete Chapter 3 TUMORE

Let me share the exact strategies that helped me and countless other players finally conquer Chapter 3 TUMORE and unlock Treachstone John Doe.

Recommended Battler Compositions

The Meta Meatshield Trio:

Tumored Battler: Fast, cheap, excellent bait for Treachstone
Hobo Battler: Alternative fast meatshield option
Builder Battler: Reliable frontline presence

DPS Carry Units:

Newell Battler: Massive splash damage, easily stackable, high HP and armor
Trebuchet: Takes huge chunks of Treachstone’s health when stacked
Lil’ X-TREME: AoE stun for dangerous peons, high DPS when stacked

Support and Utility:

Healorb Battler: Keeps units alive during Treachstone’s devastating attacks
B. Money: Quickly builds economy for critical deployments
Cyber Battler: Decreases resistance of enemies

Units to AVOID in Chapter 3 TUMORE

Micspammer Battler and Operator can easily wake up Treachstone prematurely. Here are other units that will hurt your chances:

Unrecommended Units:

Most debuffing and DoT units (Treachstone is Omni-Immune)
Non-gravity projectile units (Iota, Ignis Battler, Lil’ Turking) – they miss Ice Fowls and hit sleeping Treachstone
Ivory (hard-countered by Ice Fowl)
Tarnished Battler (obliterated in phase 2 too quickly)
Bomb-based units (Arson, Bomb, Kamikaze Battlers) – get extinguished

The Winning Strategy Formula

Here’s my personal strategy that got me through Chapter 3 TUMORE 1-star:

Early Game (0-2 minutes):

Deploy cheap meatshields immediately to handle peons
Build up economy with B. Money or similar units
Start stacking Newell Battlers behind meatshield wall
Add Trebuchets in safe backline positions

Mid Game (2-4 minutes):

Maintain constant meatshield rotation
Continue stacking DPS (aim for 3-4 Newell Battlers minimum)
Add Healorb Battler before major enemy waves
DO NOT use cannon or hit Treachstone yet

Late Game/Treachstone Phase (4+ minutes):

Ensure you have maximum DPS stack ready
Awaken Treachstone with cannon or controlled damage
Focus all damage on Treachstone immediately
Replace fallen meatshields constantly
Use Lil’ X-TREME stuns to control dangerous peons

Phase 2 Burst:

When Treachstone hits 50% HP, prepare for phase transition
Spam remaining money on meatshields
Your DPS stack should kill him before he wipes your team
Don’t panic – trust your preparation

Common Mistakes That Will Make You Fail

After watching hundreds of players struggle, here are the top mistakes to avoid:

Mistake #1: Attempting TUMORE Too Early

Entering TUMORE before finishing Normal 3-stars for Chapter 1 and 2 forfeits easy EXP and a stabilizing extra unit that simplifies TUMORE clears. Be patient and build your foundation first.

Mistake #2: Misreading Collab Requirements

Always cross-check Forsaken’s collab menu and The Battle Bricks panel rather than relying purely on external summaries. I’ve seen countless players complete the wrong chapters because they didn’t verify their specific requirements.

Mistake #3: Poor Economic Management

Many players waste money on unnecessary units or deploy expensive units too early. Master economy management by:

Only deploying what you need for current threats
Saving money for critical moments (boss spawns)
Using economy boosters like B. Money strategically

Mistake #4: Neglecting Unit Levels

Level units based on utility, not ease: among starters, prioritize Sword over Battler and Trowel for reliable early DPS and lane control. Every level matters in TUMORE difficulty.

Mistake #5: Awakening Treachstone Prematurely

Using units that fire projectiles carelessly or using your cannon too early will wake Treachstone before you’re ready. This single mistake causes more failed runs than anything else.

Alternative Method: The “Tumor Mode” Easter Egg

There’s been some confusion about an alternative method referenced in early guides. Let me clarify what this actually is:

The Satirical “Tumor Mode” Guide

Some guides humorously mention “Tumor Mode” accessed by joining the game, rejoining during load, and spam-clicking the cog icon during loading to trigger a hidden effect. This is largely a community joke or easter egg rather than a legitimate unlock method.

The Joke Elements:

Claims you need to beat “Star Extreme Mode”
Mentions fictional “400,000 Robux” cost
Part of the community humor surrounding the game’s difficulty

The Reality: The actual unlock method is through TUMORE difficulty (spelled with an ‘O’) and completing the official badge requirements. Don’t waste time trying to access satirical “Tumor Mode” – focus on the legitimate TUMORE progression path.

The Battle Bricks vs Forsaken: Which Community is Harder?

Community discussions note concerns that if Forsaken players struggle with Battle Bricks Normal mode, TUMORE difficulty for the Treachstone skin could create frustration. Let me address this controversy:

Community Perspectives

The Battle Bricks Community View:

More experienced with tower defense mechanics
Used to strategic planning and unit management
Generally more patient with grinding and optimization

The Forsaken Community View:

Primarily horror/asymmetrical gameplay background
Less experience with tower defense mechanics
More action-oriented playstyle

The Truth: Both communities bring different strengths. Forsaken players excel at quick decision-making and adaptation, while Battle Bricks veterans understand long-term strategic planning. The Treachstone John Doe unlock bridges both worlds – you need Forsaken dedication and Battle Bricks skills.

Is Treachstone John Doe Worth the Grind?

After spending 30+ hours completing all requirements, here’s my honest assessment:

Pros of Obtaining This Skin

Visual Impact:

One of the most visually impressive John Doe skins
Unique frozen/horror aesthetic stands out in matches
Uses Treachstone’s epic 2nd phase appearance
Instantly recognizable as a prestige skin

Bragging Rights:

Shows dedication and skill (not pay-to-win)
Rare enough to turn heads in lobbies
Part of limited-time collab (future scarcity)

Gameplay Experience:

Cons to Consider

Time Investment:

20-40+ hours of gameplay across both games

Potential frustration during difficult TUMORE attempts

Skill Requirements:

Not accessible to casual players
Requires strategic thinking and patience
May need multiple attempts to complete requirements

Availability Uncertainty:

Treachstone John Doe is listed as “UPCOMING CONTENT” and is NOT in game yet as of the last wiki update
Release timing may vary
Requirements could change upon official release

My Verdict

Absolutely worth it if you:

Enjoy both Forsaken and tower defense games
Want exclusive collab skins
Appreciate challenging gameplay
Don’t mind time investment

Skip it if you:

Only play Forsaken casually
Dislike tower defense mechanics
Have limited gaming time
Prefer instant gratification

For players serious about Forsaken, this skin represents one of the best prestige unlocks available. The combination of visual appeal, rarity, and skill demonstration makes Treachstone John Doe a must-have for dedicated John Doe mains.

Frequently Asked Questions

Is Treachstone John Doe available right now in March 2026?

The availability varies by server and update schedule. The wiki lists Treachstone John Doe as “UPCOMING CONTENT” that is NOT in game yet, though this may have changed. Check your in-game collab menu in Forsaken to see current availability.

Can I unlock Treachstone John Doe without playing Battle Bricks?

No, this is a cross-game collab skin that specifically requires completing challenges in The Battle Bricks. There’s no way to unlock it through Forsaken gameplay alone.

How long does it take to unlock Treachstone John Doe?

For experienced Battle Bricks players: 15-25 hours. For complete beginners: 30-50 hours. Skill level, unit roster, and available playtime heavily influence completion time. Most players complete it within 2-4 weeks of dedicated play.

What happens if I complete Chapter 4 but not Chapter 3 TUMORE?

This depends on your specific requirements. Some players only need Chapter 4 completion, while others need both. Always verify in your collab tracker to ensure you’re completing the correct objectives.

Do I need to spend Robux to get Treachstone John Doe?

No! While you can buy Bricks with Robux to speed up progression in Battle Bricks, the skin itself is obtainable completely free-to-play through badge achievements. Patient players can complete all requirements without spending real money.

Will my progress reset if I don’t play for a while?

No, your chapter completions and badges are permanent. Take breaks as needed – your progress will be waiting when you return.

Can I get help from other players for difficult stages?

The Battle Bricks is a single-player tower defense game, so you cannot get direct help during stages. However, you can learn strategies from the community, watch guides, and optimize your approach based on others’ experiences.

What if the requirements change after I start working toward them?

Game developers typically give advance notice for major requirement changes. If requirements do change, previously completed achievements usually still count. Monitor both games’ official announcements for updates.

Is there a difference between “Treachstone” and “Treacherous” John Doe?

Yes! “Treachstone” is the correct name for the Boss and the skin. Some guides mistakenly use “Treacherous” (which is the stage name where Treachstone appears). The actual skin is called “Treachstone John Doe.”

Can I trade for this skin instead of unlocking it myself?

No, Treachstone John Doe is a badge-locked collab skin that must be earned personally. It cannot be traded or purchased from other players, making it a true prestige unlock.

Final Thoughts

Unlocking Treachstone John Doe represents one of the most rewarding challenges in the Forsaken collab ecosystem. This isn’t just another skin purchase – it’s a testament to your dedication, strategic thinking, and mastery of two completely different Roblox games.

The journey from complete beginner to proud Treachstone John Doe owner transforms you from a casual player into a skilled veteran. You’ll learn tower defense fundamentals, master TUMORE difficulty strategies, and join an elite group of players who’ve conquered The Battle Bricks’ toughest content.

Remember: every expert was once a beginner who didn’t give up. Your first Chapter 3 TUMORE attempts might end in frustration, but each failure teaches you something new. Stack those meatshields, position your DPS carefully, and don’t awaken Treachstone until you’re absolutely ready.

When you finally see that Treachstone John Doe skin unlocked in your Forsaken inventory, all those hours of grinding, strategizing, and perfecting your approach will feel worth it. You’ll have earned one of the most exclusive and visually stunning skins in the game – and you’ll have the skills to dominate both The Battle Bricks and Forsaken.

Now stop reading and start playing! That frozen terror isn’t going to unlock itself. Good luck, and I’ll see you in the frozen wasteland of TUMORE mode!
