A Guild of Fishermen Job tasks you with activating your Hunters Arm two times. In this guide on How To Activate Your Hunters Arm In Wild Hearts we explain how the mechanics of the request works so you can activate your Hunters Arm successfully, complete the task, and get the rewards for finishing the mission.
At the beginning of the game, during the tutorial section of Wild Hearts, you are shown a strange device on the hunters arm. This device is then used to construct platforms so you can climb to higher locations and advance the story. However, simply standing in the town and trying to build Karakuri will not have any effect and will not progress the mission.
How To Activate Your Hunters Arm In Wild Hearts
In order to complete the Guild of Fishermen Job called the Hunter’s Mighty Arm, you must mount the creature and use the Hunters Arm attack. This work combines two different techniques. First, you must jump toward the creature and mount the creature. This is done in a similar fashion to climbing. Run toward the creature, jump, and hold R1/RB. This will mount the creature. You can then climb around and attempt to hold on.
The second part of this is to target an exposed weak point on the beast. These are shining blue areas that have been damaged and exposed. If you are mounting the creature and you are near to one of these spots, the Hunters Arm attack prompt will appear. This is L2/LT on PlayStation and Xbox, the same key that does your Hunter Sense.
Repeat this process twice to complete The Hunters Mighty Arm and finish the quest.
