Fishing and cooking on ech0scape is very simple and it goes relatively quick
*Tele to catherby. From here head east to fishing spots.
What to do:
*Go to the net fishing spot until lvl 30 or 40 fish whichever lobsters level are. Once you reach 30 or 40 fish, fish lobsters. To fish lobsters you have to use your lobster pot on the fishing spot. Keep using it on the spot to get lobsters. I am only 53 fish so cant say much more I will update fish once i reach further levels. For cooking use your shrimps on the range next to the bank. Yes you have to keep using on range its annoying i know. Do this until 40 cook than do lobbies. Hope this guide helps and good luck
