Count only crab-tagged evolutions, use the character-screen meter, and route stable crab pieces first: Antennae, Shell, Exoskeleton, Moulting, Arms into Pincer and Pistol Pincer, plus Arthropod Legs into Scuttle or More Legs. Reaching 7 unlocks the Convergent Evolution roll, but it may still take another offer to appear.

Read guide| Question | Practical answer | What to watch |
|---|---|---|
| What actually counts? | Only evolutions with the small crab icon advance the Carcinisation meter, and the character screen shows the running total. | Do not hand-count every shell-looking card or every affinity point. |
| How many current evolutions affect it? | An official August 15 developer reply says 10 current evolutions affect Carcinisation. | Treat 10 as the current live count, not a promise that every crab-looking evolution or future update uses the stat. |
| What is the clean public route? | Antennae, Shell, Exoskeleton, Moulting, Arms into Pincer into Pistol Pincer, and Arthropod Legs into Scuttle or More Legs are the clearest public pieces named in current player advice. | This route reaches 7 through stable branches instead of praying for a mystery legendary too early. |
| What breaks the attempt most often? | Taking Fur or Scales too early, skipping Arms or Legs follow-ups, or assuming Convergent Evolution appears immediately after 7. | Reaching 7 unlocks the offer; it does not force the next level-up to show it. |
If the real goal is The Crabtain rather than only Carcinisation 7, solve survival first and treat Convergent Evolution as late upside instead of the entire run.

Carapace, pincers, legs, shells, and food-rarity tradeoffs. Strong when the run is stable; dangerous in Pressure 20 or damage-sensitive routes if taken while behind.
