Pro Fishing Tips

Watch the Shadow Size: Giant fish shadows indicate rare/epic fish. If a shadow is small, you can pull your rod out early to reset the shadow without losing bait.
Use Mermaid Fish Attractor: You can craft this at the alchemy bench or redeem it from active codes. It boosts the bite rate of epic/legendary fish by +50% for 3 minutes.
Upgrade Your Rod: Standard rods have a high chance of line snapping when attempting to reel in legendary swordfish. Upgrade your fishing rod to at least Level 4 before trying to catch ocean swordfish.
