Embark on a captivating side quest in the vibrant world of Monster Hunter Wilds to unlock the coveted Monster (Squid) Hunter trophy or achievement. This guide provides a comprehensive walkthrough to help you snag this unique reward.
While fishing might seem like a leisurely pastime, it plays a crucial role in this particular achievement. It unlocks a unique questline, providing you with the necessary equipment. To begin, you must progress through Kanya's fishing quests. This involves completing several side quests, each requiring you to gather specific items for her:

Seeking the Goldenfish: Locate the Goldenfish in underwater pools within caves. Area 6 of the Scarlet Forest is a good starting point. Use either the Golden Bughead or Common Wood Minnow baits. Fallow weather conditions increase your chances of finding it.
Fishing for Favor: Next, catch the Gravid Bowfin. The Scarlet Forest base camp offers a convenient location, but you'll need "Plenty" weather conditions. Equip the Emerald Jitterbait and cast your line.
The Catch of a Lifetime!: Now, Kanya tasks you with catching any large fish that triggers the reeling minigame. The Tuna in Area 17 of the Scarlet Forest is a reliable option.

After completing these quests, Kanya will request you to undertake the "Razzle Dazzle" quest. This is where you'll finally obtain the Monster (Squid) Hunter trophy/achievement:
Final Quest: Head to Area 17 of the Scarlet Forest. Ensure "Downpour" weather conditions during "Inclemency" (use the grill or camp to adjust weather). Wade into the deepest part of the lake. Spot the squids (if none appear, fast travel and return). Equip the Tentacle Jig and begin fishing. Target the Goliath Squid—look for the blue glowing shells. Once you hook a squid and the reeling minigame starts, reel it in to claim your reward and unlock the trophy/achievement.
