Transformice is Atelier 801's free multiplayer platformer where a room full of mice race to grab a piece of cheese and carry it back to a hole, while one player is chosen as the Shaman and builds the route with planks, boxes, anvils and balloons. The Shaman scores by saving other mice, and after 1,000 saves hard mode unlocks, then divine mode at 5,000 saves with at least 2,000 of them in hard mode. Five skill trees, Spiritual Guide, Wind Master, Mechanician, Wildling and Physicist, hold 15 skills each across six branches, so what a Shaman can summon changes considerably between two players at the same level.
Boss fights are where Transformice tests everything you've learned. This guide covers strategies for bosses across all areas, organized by progression order. For general combat techniques, see our combat guide.

|---|---|---|---|
| Vanilla | Easy | Wind Master | Big Box |

Vanilla Bosses
Area difficulty: Easy Recommended level: Any level, official maps only Recommended build: Wind Master with Big Box
Strategy
The first bosses teach core combat mechanics. Focus on learning patterns rather than dealing damage. A round is won by touching the cheese and then reaching the hole. This is your primary tool here.
Key tips:
- Don't rush. Learn the attack patterns first.
- Use Cheese and hole scoring to create safe windows.
- Big Box is enough to handle everything here.
Bootcamp Bosses
Area difficulty: Moderate Recommended level: Advanced platforming, no Shaman Recommended build: Wind Master with Big Box
Strategy
Early game bosses test your understanding of Shaman summoning. Players who skipped learning this mechanic will hit a wall here.
Key tips:
- Shaman summoning is critical for these fights.
- Farm Big Box upgrades if you're struggling.
- Consider switching to Wind Master if your current setup isn't working.
Racing Bosses
Area difficulty: Hard Recommended level: Any level, 11 or more mice for ranked results Recommended build: Spiritual Guide with Little Plank
Strategy
Mid-game bosses are the major skill check. They combine multiple mechanics and punish players who rely on a single strategy.
Key tips:
- You need both Cheese and hole scoring and Nails and joints mastery.
- Little Plank makes a significant difference. Get it before attempting these.
- See our combat guide for advanced techniques.
Survivor Bosses
Area difficulty: Very Hard Recommended level: Any level, adversarial Recommended build: Spiritual Guide with Little Plank
Strategy
Late-game bosses are serious challenges. Build optimization matters as much as mechanical skill.
Key tips:
- Make sure your build is fully optimized.
- Little Plank at max upgrade is recommended.
- Study each boss's attack patterns. Most have 2-3 phases.
Defilante Bosses
Area difficulty: Extreme Recommended level: Any level, cooperative Recommended build: Spiritual Guide with Little Plank
Strategy
Endgame bosses are the ultimate test. They require mastery of all combat systems and an optimized build.
Key tips:
- Top-tier build with best-in-slot gear is mandatory.
- Master every mechanic. See our combat guide.
- These fights reward patience and pattern recognition above all else.
General Boss Tips
- Learn before you fight: Spend your first attempt observing attack patterns. Don't try to win on attempt one.
- Match your build: Some bosses favor certain builds over others. Don't be afraid to switch.
- Upgrade your equipment: A max-upgraded Little Plank trivializes fights that seem impossible with weaker gear.
- Use Cheese and hole scoring: The core combat mechanic is your best defensive tool in every boss fight.
- Check the walkthrough: Our walkthrough tells you when you're ready for each boss.
