Hello Brystal Blades! I read recently on this board that once you get a load of three shells you can click to different characters while talking to the guy who needs the shells to make breathers and he will credit you for having more than one load and make lots of breathers. I never tried it, but someone said it works great. Let me know if you try it and it works for you.
Also, you can turn up your monster spawn to frequent in the game options menu and hang around in the water outside Brimloch to see if you get more crabs.
Hope this helps you!
Welcome to this nice place!!
