LocationsFisch

Overview[1]

The Grand Reef is a location in the First Sea found west of Roslit Bay and north-west of Forsaken Shores. It consists of a small central island with three smaller islands located nearby, all within a large whirlpool beneath a raging storm. In the center of the main island is a hole that, when stood on, teleports the player to Atlantis. Beneath the small islands is a coral reef consisting of many undersea structures, one of which is a large blocked-off door that, when destroyed with TNT, opens a maze where the player will find the Heart Of Zeus.

Patch history

This is the first island which introduced lightning strikes above the island, causing sound effects to appear. As a result, the Electric Mutation (1.45x) appears to be more common, with a 15% chance. Grand Reef isn't recommended for new player due to the negative progress speed when reeling a Legendary (-60%) or Mythical (-75%). The Grand Reef was one of the best fishing spots for farming until its nerf in the Mariana's Veil update. This island is one of the best spots for catching supply items, such as Fish Barrels, Common Crates and Bait Crates. Using known better baits like Super Flakes, Shark Heads, or Weird Algae has no major effect on the fish caught. Using Fish Heads is better for the location. The Grand Reef was part 1 of the upcoming Atlantis Update on January 25th, 2025. There is a hidden text in Latin, saying "The mother of all monsters". It was speculated to be a tease for the Atlantis Update. Category:Locations Category:Grand Reef
