I initially thought this small crustacean had evolved a rocky shell mainly for defensive purposes.

However, I was quick to revise my opinion after I was almost flattened by a group of Boulder Crabs rolling down a hill.

• Boulder Crab shines against high-danger encounters; talent synergy strongly shapes its tier.
• Prioritize raw damage in early acts, swap toward survivability in mid–late game.
• Compare with similar-role creatures (taming difficulty, food preference) before locking it into your deck.
