Normal-type moves such as Cut, Vice Grip, or Uproar is resisted by Rock and Steel-types, as well as completely failing against Ghost-types. Crawdaunt is a Water-Dark type, therefore the attack will affect Crawdaunt normally. 

For Normal-type Pokémon, however, they are immune to Ghost-types and weak to Fighting types.
