The Tall Elk (Jayma the Hunter) | Walkthrough Far Cry Primal Guide

Activate hunter vision after starting the mission (it is available during night) and follow the fireflies. After a moment you will reach the place with the moose. Don't get below yet. You will have a perfect view of the valley. Udam warriors will appear there as well. You can give them some time to weaken the moose. However, watch out so that they don't kill him. Join forces with the moose and kill Udam warriors (you can easily do it with a bow from the rock shown on the picture). Then follow the moose.

Walk towards the moose from behind. This will give you a few seconds of advantage.

Frontal attack is dangerous. First you should use your strongest animal to distract the moose. Then use the strongest weapon (it will probably be the spear) and throw it at the head of attacked moose. Depending on the selected animal you might have more time to perform some more attacks - for example, if you have already tamed a cave lion. Otherwise you should escape to the sides from the charging moose and then quickly throw the club at it or shoot the bow. Depending on previous wounds and your accuracy, the moose should fall after a few accurate throws. Additionally, if the hunting is troublesome for you, you can first learn how to create traps that will make killing the moose even easier (Vicious traps skill).
