The huge squid in "Monster Hunter: The Wilderness" is a special fish that is very difficult to catch in the game. If you want to catch huge squid, you can fish at the lakeside of Crimson Forest Area 17. There is a relatively high probability that huge squid will appear at night in rainy weather, and you will have to wait a long time.
How to catch giant squid in the wilderness of Monster Hunter
After completing the fishing series of Kanya and obtaining the [Tenet Bait], at night at the fishing spot on the lakeside of Crimson Forest 17, it is best to get fishing in heavy rain (the capture net is invalid). You need to shake the bait and let it bite the bait, and general-purpose bait can also succeed.
The probability of rainy days at night is extremely high, but you must be patient. There will be a long period of struggle and the squid will not jump. (Put a picture of the big gold I fished as a souvenir.)
