In Monster Hunter Wilds, no two days are ever the same. There’s always something new around the corner. A big part of that is the monsters. Some are small and manageable. Others, like Uth Duna, are much tougher. Uth Duna is a large water-based monster. It’s not one you can just run into by chance. You’ll need to know where and when to look. But once you find it, you can bring it down with the right plan. Here’s what you need to know.

You can only find Uth Duna in the Scarlet Forest. It doesn’t show up on sunny days or when the skies are just cloudy. It only appears during a big downpour. If the weather isn’t right, don’t bother looking for it. But you do have another option. You can take on one of these two quests that force Uth Duna to appear:
Uth Duna in Monster Hunter Wilds has fin-like armor covering its body. This armor blocks most attacks. At the start of the fight, you won’t be able to hit just anywhere. Focus on its face and tail. Once those areas take enough damage, the armor will break. Then you can hit other parts of its body. The best spots to target are the head, tail, and forelegs. These are weak areas that take more damage. The fight happens mostly in the water. That slows you down a lot. It’s harder to move, roll, and dodge. So be extra careful. Uth Duna is not just fast—it also hits hard.
Uth Duna uses a mix of close and wide attacks. These are the main ones you’ll see:
There’s a dam in the area where Uth Duna fights. It can be used against the monster. When Uth Duna stands near the dam, use your Slinger to shoot at the group of logs above. After a few hits, they will break. This causes the dam to burst, which deals a lot of damage to the monster. It’s a nice trick to turn the fight in your favor.

Uth Duna is very sensitive to certain effects. If you use weapons or tools that cause Stun, Poison, or Sleep, the fight becomes much easier. These conditions stop Uth Duna for a short time and give you room to heal or hit back.
There’s no shame in calling for backup. Use an S.O.S. flare to bring in help. Also, check your gear. If your weapons or armor are not upgraded, you’ll be at a big disadvantage.
Here are the rewards you can get after defeating Uth Duna:
