I remember seeing a topic about this about a month ago . The exact quote from the book that made me go wasTickle the monster ' s ribs , he muttered , repeating the girl ' s words . If I knew how . My knowledge in matters of marine teratology remains very limited . Interesting . According to what I know , there are a lot more monsters in the sea than on the land , in terms of both individuals and species . It seems to me then that it ' s good hunting grounds for a witcher . That ' s not so . Why ? The spread of humans to the ocean , he replied , clearing his throat and turning his head , is too recent . Witchers were especially necessary on land at the time of the first settlement . We are not adapted for combat with sea creatures , even though the most aggressive creatures abound underwater , it ' s true . The capabilities of witchers aren ' t enough against these sea monsters . These creatures are either too large or too wellprotected behind their shells or finally too much at ease in their element . Or all three at once . From
