Trapped
Head on over to Wogah's map marker to the east of the village.
His dwelling will be located under the hill.
Approach the entrance to trigger a cutscene.
After Wogah mistakes you for an Udam and gives you a shower and insults you, your are now in the, quite literal mission named Trapped. First, set fire to any of your weapons by using animal fat. If you don't have animal fat, there are some scattered around this cave.
Light the pieces of wood and branches in the middle of the room. If you are having trouble finding it, enabling hunters vision will show it. After burning them, you can now jump down. You can jump into the water and climb out of it to avoid damage instead of landing on the ground and taking damage.
Be warned though, this area has a jaguar in it. They can be killed easily with fire though so light your melee weapons and keep waving / hitting the cat with it.
After dispatching of the jaguar, follow the trail to find a dead jaguar with the grappling hook lodged in it.
The grappling hook allows you to climb specific areas marked by the grappling hook icon.
With the grappling hook, head back to the main area and look for the spot where you can grapple to. A trail can be seen if hunter vision is enabled.
Climb up to reach the next area.
Keep moving forward until you will have to drop down into a pit with 3 jaguars.
Before attempting to go down, you should have a weapon that is lit with fire. You can do this upon landing but it is dangerous. After landing, go after the cats with your weapon. Dispose of them however you wish.
Find the next grappling point and climb to the exit where you will complete the mission and continue to Wogah's next mission which will actually make him join the tribe.
