Notes:* Indicates a Rare fish(1) Funky Sea Snail is an item that will summon a Bitestone Fishbrul that drops a Salmon Lure when killed.(2) Swollen Murloc Egg is an item that will spawn a Murloc NPC, Swamprock Tadpole, that grants the buff Blessing of the Murlocs, increasing your chance to fish up Mountain Puffer.(3) Rotten Fishbone is an item that will attract a Druid NPC (Lorlathil Druid) that casts the The Cat's Meow buff on you, increasing your chance to fish up Ancient Mossgill.(4) Drowned Thistleleaf is an item that will grant the buff Blessing of the Thistleleaf, increasing your chance to fish up Thorned Flounder.(5) Skrog Toenail is an item that will summon a Salteye Skrog-Hunter that drops a Aromatic Murloc Slime when killed.(6) Rusty Queenfish Brooch is an item that is required to see Ghostly Queenfish pools in Azsuna.(7) Using Sleeping Murloc will awaken a Confused Seerspine Murloc, who will run around briefly and drop some Seerspine Puffer into the water.(8) Moosehorn Hook is an item that increases your chances to catch rare bait in Stormheim, rather than fish.(9) Ancient Vrykul Ring is an item that is required to see Oodelfjisk pools in Stormheim.(10) Message in a Beer Bottle contains Axefish Lure when opened.(11) Using Stunned, Angry Shark will spawn a Landlocked Shark, which will yield Seabottom Squid when killed. Using it on land makes it much less dangerous than in water (hits quite hard).(12) Decayed Whale Blubber is an item that attracts flies - Ravenous Fly can be looted from these.
My personal experience with this achievement.I've been reading in various places about the amount of fishing required for this achievement - guides say ~12 hours of fishing, and various posts say hundreds of casts/hours spent on a single rare.If I had to give only one piece of golden advice: DO NOT FISH FROM OPEN WATER!I obtained this achievement in a fraction of the time that has been previously noted when fishing from open water. Below I've listed the steps I took.
I hope this advice is helpful to you! My take home point is, fish from pools as much as possible - it saves a HUGE amount of time! The added bonus is that you'll end up with a lot of useful fish that can be sold on the Auction House or used in Cooking recipes.If you are in not the biggest hurry (or even if you are) I find a great strategy is to set out to do World Quests, and fish from any pools you come across. You can cover most of the rare fish this way.
Bigger Fish to Fry is a requirement to obtain the Fishing artifact - the Underlight Angler!There are a number of Rare fish in Legion, and items (bait or otherwise) that will help you catch them.The Rare fish and items to catch them are zone specific (although some are obtainable on any shoreline of the Broken Isles).Rare FishThere are 18 rare fish coming in Legion that can be fished up. Each rare fish grants +5 to Fishing skill when used, consuming it in the process.
Fishing Bait and ItemsSome of the items that help you catch Rare fish will spawn and NPC that grants a fishing buff; others contain bait, or spawn NPCs that drop bait.
Each zones baits are now purchaseable from the fisher friends, for their respective currencies, with Impus selling the coastal baits.
