What you will need:
A way to protect yourself.
A near empty cart.
A pet to hold stuff, as well as food and an incubator.
A Fishing Rod.
Plenty of Bait.
How to Fish:
Step 1: Do the fishing quest, or make sure you have the
Fishing Rod in your inventory.
Step 2: Buy as much
Bait as you think you can use without being unable to arrange fish, for this purpose I bought 3000.
Step 3: Make sure you have an
Incubator and enough
Pet Food to last you for as long as it takes you to fish, generally 10-20 should be more than enough.
Step 4: Secure a way to protect yourself while fishing, either a homun (which generally sucks for the 2nd fishing spot due to its ADD Ai.), or be able to kill mobs manually if needed.
Step 5: Make your way to the fishing spot. Not dying is key.
Step 6: Find yourself a comfortable position to set up. Have your character sit a little bit away from the fishing spot, yet have it still on screen. Now align the first text box above the fishing spot, so that the 'next' button overlaps it. Next have the menu button so that your response overlaps the next or close button.
Step 7: Move your mouse over the fishing spot and mass click until you have carpal tunnel and sue the server for medical injuries that was your fault in the first place for fishing. (This works especially well for people with laptop mouses / touchpad mouses or game pads, since you don't have to worry about the mouse moving after mass clickings.)
Notes: Keep in mind your weight capacity, along with your pet and homuns hunger. Rotate stuff between cart, inventory and pet as needed.
Your setup should look something like this.
Lastly, don't suck.
Now you should be full of fish.... either repeat or take a break so you do not develop severe medical injuries such as carpal tunnel. McDonalds may have been sued for making people fat, but... okay so it is the same situation, but that is a jerk move on your part.
Step 8: Don't sue the server, jerks.
