How do you unlock the Legendary Fish for the Survivalist Challenge 10?

To unlock the Legendary Fish for Survivalist Challenge 10 in Red Dead Redemption 2, you must first complete the A Fisher of Fish mission, which is given by Jeremy Gill. This mission becomes available in Chapter 4 after completing the mission ''A Fine Night of Debauchery.'' Jeremy Gill is located at his cabin on the northeastern shore of Flat Iron Lake, near the town of Rhodes. Once you meet him, he will provide you with a map of Legendary Fish locations and a special lure, which is essential for catching these rare fish.\n\nBefore attempting to catch any Legendary Fish, ensure you have the Special Lake Lure, Special River Lure, and Special Swamp Lure. These lures can be purchased from the bait shop in Lagras, located in the Bayou Nwa region. Each lure is designed for specific types of water bodies, so make sure to use the correct one depending on the fish''s habitat. For example, the Legendary Bluegill is found in Lake Don Julio, so you will need the Special Lake Lure to catch it.\n\nOnce you have the necessary lures, consult Jeremy Gill''s map to identify the locations of all 13 Legendary Fish. Each fish is tied to a specific region and body of water. For instance, the Legendary Smallmouth Bass is found in O''Creagh''s Run, a small lake in the Grizzlies East region. Travel to the marked location and look for ripples or splashes in the water, which indicate the presence of a Legendary Fish. Cast your line into the water using the appropriate lure and wait for the fish to bite.\n\nCatching Legendary Fish requires patience and skill. When the fish bites, press the appropriate button to hook it. Then, use the left stick to reel in the fish while keeping tension on the line. Avoid reeling too quickly, as this can cause the line to break. Instead, alternate between reeling and letting the fish tire itself out. Each Legendary Fish has unique behavior, so adapt your strategy accordingly. For example, the Legendary Muskie in Lake Isabella is particularly aggressive and will require quick reflexes to reel in.\n\nAfter catching a Legendary Fish, you cannot carry it in your inventory like regular fish. Instead, you must mail it to Jeremy Gill using a post office. Visit any post office in the game, such as the one in Valentine or Saint Denis, and select the option to mail the fish. Jeremy will send you a reward and a letter acknowledging your catch. Repeat this process for all 13 Legendary Fish to complete Survivalist Challenge 10.\n\nOne common challenge players face is locating the exact spot where the Legendary Fish spawns. If you are having trouble finding the fish, try visiting the location during different times of day or in different weather conditions. Some fish are more active during specific times, such as dawn or dusk. Additionally, ensure you are using the correct lure and casting your line in the right area. If the fish still does not appear, leave the area and return later, as this can reset the spawn.\n\nAnother tip is to save your game before attempting to catch a Legendary Fish. This allows you to reload if something goes wrong, such as the fish escaping or the line breaking. Additionally, make sure your fishing rod is in good condition and that you have plenty of bait and lures. If you run out of lures, you can purchase more from the bait shop in Lagras.\n\nIn summary, unlocking the Legendary Fish for Survivalist Challenge 10 involves completing the A Fisher of Fish mission, obtaining the necessary lures, and carefully following the steps to catch and mail each fish. Pay attention to the specific requirements for each fish, such as the correct lure and location, and be prepared for a challenging but rewarding experience. With patience and persistence, you can complete this challenge and earn the title of Master Fisher in Red Dead Redemption 2.
