How To Beat TUMORE Mode & Unlock Treachstone John Doe 2025 – Forsaken x Battle Bricks Guide

How To Beat TUMORE Mode & Unlock Treachstone John Doe — TUMORE is The Battle Bricks’ hardest difficulty where enemies shift into alternate forms and stage magnifications/base HP are significantly increased, so clears demand tighter summon cycles and stronger unit investment than Normal mode. To enable TUMORE, click the Tumore logo on the game’s load screen to reveal the difficulty toggle before routing star attempts.

Treachstone John Doe is tied to the Forsaken x Battle Bricks collab and is documented as achievable via the “Chapter 4 – Utopia” badge, though community threads also note panels that require Chapter 3 Tumore (≥1 star) plus Chapter 4 Normal (≥1 star), so confirm the exact checklist in your live collab tracker. This guide walks through unlocking the mode, safe team comps and summon cadence for Tumore, and the badge path needed to secure the Treachstone skin efficiently.​

What TUMORE mode is

• TUMORE converts all enemies into their alternate forms, doubles every stage’s magnification values, and increases enemy base HP by 100%, massively raising DPS and sustain checks versus normal/casual.​
• Chapter star tiers exist in TUMORE (1–3 stars), with higher stars demanding far better unit levels and routing; community runs regularly discuss two‑ and three‑star clears for key stages like Chapter 1‑30 Deathbringer.​

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 is not visible; this is the common access method for newcomers arriving from the Forsaken collab.​
• Once unlocked, difficulty toggles allow switching between Casual, Normal, and Tumore, with Tumore being the endurance mode recommended only after building a strong early roster.​

Treachstone John Doe: what it is

• Treachstone is a named boss in Battle Bricks and appears in Forsaken as a premium collab skin for John Doe, thematically tied to the same character and fight identity.​
• Unlike many John Doe skins that keep the face texture, Treachstone alters the facial appearance and presentation to match the Battle Bricks theme.​

How to unlock Treachstone John Doe (requirements)

• Collab requirements noted on Forsaken community documentation say Treachstone John Doe is “achieved by getting the Chapter 4 – Utopia badge” inside The Battle Bricks, meaning a Chapter 4 completion trigger is involved.​
• Multiple community threads also mention a combined requirement flow: complete Chapter 4 on Normal (≥1 star) and Chapter 3 on Tumore (≥1 star), suggesting both normal and Tumore progress are tracked by the Forsaken collab panel.​
• Because published notes vary between “Chapter 4 Utopia badge only” and “Chapter 3 Tumore + Chapter 4 Normal,” verify your current in‑game collab tracker in Forsaken and The Battle Bricks menu to confirm the exact checklist for your account region and patch.​

Zero‑to‑hero plan (concise)

• Finish Chapter 1 on 3 stars in Normal first to stabilize EXP and unlock an additional unit, giving a stronger springboard for Tumore routing.​
• 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.​
• With TUMORE unlocked, target Chapter 3 (≥1 star) and Chapter 4 (Normal ≥1 star) if your collab panel lists both, or Chapter 4 Utopia if your panel shows that single requirement.​

Core teambuilding and leveling

• Level units based on utility, not ease: among starters, prioritize Sword over Battler and Trowel for reliable early DPS and lane control, then decide Battler vs Trowel by your playstyle.​
• Meatshielding is extremely effective from Chapter 2 onward; keep cheap summonables on cycle to stall variants while your carries scale damage and special effects.​

TUMORE loadout principles

• Expect health and damage spikes from doubled magnifications; stack a front row of cheap meatshields with one or two mid‑cost DPS anchors and a late‑game boss shredder.​
• On high‑risk bosses (e.g., C1‑30 Deathbringer and later extremes), community often swaps in specialized carries for burst phases; treat two‑ and three‑star Tumore as separate routing problems.​

Chapter routing tips

• Chapter 1 Tumore can be blitzed if Normal rosters are strong; focus on consistent meatshield uptime so alt‑form elites do not breach while carries ramp.​​
• 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.​
• 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.​

Practical difficulty management

• If struggling to find TUMORE, repeat‑click the tumor logo at launch until the mode toggle appears; this is frequently cited by new collab participants.​
• If failing star thresholds, shift back to Normal to farm EXP and unlocks, then re‑route Tumore with tightened summon cycles and higher unit levels.​

Common mistakes to avoid

• Entering Tumore before finishing Normal 3‑stars for Chapter 1 and 2, which forfeits easy EXP and a stabilizing extra unit that simplifies Tumore clears.​
• Misreading collab requirements; always cross‑check Forsaken’s collab menu and The Battle Bricks panel rather than relying purely on external summaries.​

Quick checklist for Treachstone unlock

• Unlock TUMORE mode by clicking the tumor logo on Battle Bricks’ startup screen.​
• Clear Chapter 1 and 2 in Normal for EXP and an extra unit to harden rosters.​
• Follow your collab tracker: either Chapter 4 Utopia badge alone, or Chapter 3 Tumore ≥1 star plus Chapter 4 Normal ≥1 star as indicated.​
• Redeem the Treachstone John Doe skin in Forsaken once the linked Battle Bricks progress flags are complete.​
