Everything is Crab Evolution Calculator and Build Planner

This lightweight planner scores a route by role coverage: damage, defense, mobility, sustain, control, and achievement utility. It does not replace live patch values, but it helps players think clearly about why a run is failing.

How to use it

Choose a playstyle, then select the evolution pillars you already have or want to chase. The planner will estimate route stability and suggest what your build is missing.

Why this tool helps during a run

Players often ask for the "best build" when the real question is simpler: why did this run die? The planner helps you spot missing roles before the next boss or biome turns that weakness into a loss.

Useful future upgrades include saved builds, local achievement tracking, one page per evolution, filterable tables, patch-version tags, and player-submitted route cards.
