Builds
Build toward Carcinisation 10 for The Crabtain. Compare the player-reported crab branches, preserve compatible choices and check the stat before committing another upgrade.
Reach Carcinisation 10 in one run. The Steam condition does not name a required genetic or pressure level. Carcinise This is a different goal: defeat the final boss in under 15 seconds. A crab-themed appearance or a fast kill does not establish Carcinisation 10.
In the linked discussion about reaching 7, LocatedEagle232 and Prof_V suggest the following branches. These are player recommendations, not a guaranteed sequence of offers or a complete current prerequisite table. Check each available card before choosing.
The reported options include Antennae, Shell, Exoskeleton and Moulting. Before changing skin or body parts, compare the requirements of the crab option you still need. The players warn about choosing Fur or Scales too early; verify the actual incompatibility instead of avoiding every non-crab choice.
Antennae · Shell · Exoskeleton
The players describe Arms leading to Pincer and then Pistol Pincer. Compare the next offered card with the attack you already use. Do not count every name in a branch as a separate point without checking the resulting stat.
The discussion describes Arthropod legs with Scuttle or More Legs. Check whether an offer adds an option, upgrades it or replaces an existing part before spending resources.
Look for Carcinisation 10 and the achievement result. If they disagree, record the game version, mode and selected evolutions before changing the route. Not even yourself asks you to be your own Main Predator; it is not a second way to complete The Crabtain.
Version 1.2 changed Chosen to offer three new Legendary Evolutions, with no upgrades or branching Evolutions. That matters when your next step depends on progressing an existing crab branch. Compare the offer with the branch you still need; a Legendary label alone does not make it the missing step. Source: Official 1.2 notes
Version 1.1 increased Convergent Evolution’s chance of finding Carcinisation-affinity Evolutions per Carcinisation point. This improves the kind of offer you are looking for; it does not promise a particular card on the next level. Keep the prerequisite check separate from the probability of receiving an eligible option. Source: Official 1.1 notes
Do not replace a useful attack solely because another card looks more crablike. First identify whether that choice progresses an available branch and whether your remaining attack can finish the next encounter. The stat target and the combat problem must both remain workable.

Do not turn the developer’s count of ten contributing Evolutions into ten compulsory selections in a fixed order. A list of contributors, the cards actually offered and the attribute shown on your character are different checks. Follow the displayed Carcinisation value when deciding how much progress remains.

The listed Crabtain condition asks you to reach Carcinisation 10 in one run; it does not explicitly add a win. Check the achievement result when the attribute reaches the target, rather than assuming that a later final-boss result is the only relevant signal. Source: Steam achievement conditions
The discussion identifies branches to inspect, which can help explain an offer you are seeing. Its stated target is seven. It does not provide a demonstrated, current sequence all the way to ten, so use it to compare requirements rather than to promise the final outcome. Source: LocatedEagle232 and Prof_V’s discussion
No. 100 Coats counts ten Moulting uses within one run. The Crabtain counts the Carcinisation attribute. A Moulting-related branch can be relevant to the crab plan without making repeated activations a substitute for checking that attribute. Source: Steam achievement conditions
Steam lists the achievement conditions.
Official Steam achievementsOddDreamsDigital states in the linked reply that 10 evolutions affect Carcinisation. That statement is not a list of ten mandatory selections or a promise that the count stays unchanged in later versions.
Developer reply about crab evolutionsLocatedEagle232 and Prof_V describe branches in a discussion about reaching 7. Their suggestions inform the checklist above; they do not prove a stable route to 10.
Player discussion about reaching Carcinisation 7: Added the 1.2 restrictions on Chosen offers and the 1.1 Convergent Evolution change. Clarified why a player route to seven does not establish a complete route to Carcinisation ten.
