Achievement Guide
The Crabtain is a build-shape achievement, not just a long-run achievement.
Current community notes describe The Crabtain as reaching Carcinisation Level 10, with a route that depends on crab-form components such as Pincer, Pistol Pincer, Scuttle, More Legs!, Shell, Antennae, and Molting. The practical job is to keep the run stable while you collect the right identity pieces.

Achievement
The Crabtain
Goal Type
Carcinisation Level 10 / crab-form build route.
Known Components
Pincer, Pistol Pincer, Scuttle, More Legs!, Shell, Antennae, Molting.
Main Risk
Overcommitting to the checklist before the run can survive.
Short Answer
Treat The Crabtain as a targeted evolution route. You are not simply trying to become strong; you are trying to become specifically crab-shaped enough to reach Carcinisation Level 10. The route needs stability first, then component completion.
Route Priorities
- Keep defensive stability high enough that you can wait for the right evolution options.
- Avoid locking into a build identity that conflicts with the crab-form checklist.
- Prioritize known required components when they appear, especially if they are hard to replace.
- Watch for Molting opportunities, because it is part of the documented component set and also ties into other achievement routes.
Why This Can Fail
The obvious trap is chasing every listed component immediately and ignoring survival. If the run is too fragile, the checklist does not matter. A safer approach is to build enough defense, movement, or recovery to keep the attempt alive while you wait for the right branch options.
The second trap is treating every crab-flavored option as equal. The known list matters. If future testing confirms exact scoring rules for Carcinisation Level 10, this page should be updated into a strict checklist.
Best Companion Pages
Read this achievement alongside Evolutions and Builds. The Evolutions index helps with component names, while Build pages help you judge whether the route is still stable enough to continue.
What We Still Cannot Confirm
The public route notes identify important components, but exact scoring details for Carcinisation Level 10 should still be treated cautiously until verified directly in-game.
