Right on Target
Kill a target 50 feet away or more using a spear.
The spear will automatically become available early in the game. Now head to an enemy outpost (the one called “Kapal Outpost” to the east of the village works great for this). Use your owl to place a waypoint on one of the idle enemies (press L1 / LB). The waypoint will show you the exact distance. When it’s at 50+ feet you must aim a little bit over the enemy’s head and throw the spear.
There are also enemies randomly roaming through the woods, so there are many possible locations to get this. The early outposts work best because the enemies don’t have any armor and will die in 1 hit from the spear.

If you mess up, simply let the enemies kill you and you’ll respawn in front of the camp.

Bullseye
Kill a target 70 feet away or more using an arrow.
You should craft the Long Bow for this. It can be crafted after building Jayma’s Hut relatively early in the game. Unlike the normal bow it will kill unarmored enemies in one hit and it’s also far more accurate on long distances.
Once you have the bow, go to an enemy outpost. The “Swaras Outpost” to the north-east of your village works great. Use the owl to place a waypoint on an idle enemy. This will show you the exact distance. When the waypoint is 70+ feet away aim a little bit over the enemy’s head and shoot your arrow.

If you mess up (alert enemies etc.) get yourself killed and you’ll respawn at the outpost.

Kanda of Faith
Climb to the peak of Pardaku Lookout and leap off.
For this you must jump off a mountain to the south of Piki Meat Outpost. There’s a small pool of water on the west side of the mountain. You need to jump from the peak into this pool.

Mark 4 Wenja
Discover the future past.
For this you must visit a cave in the east of the big frozen area. The cave is marked with a “?” symbol on the world map and it’s at the start of a river. Go inside the cave and you’ll see the purple skeleton of a blood dragon. This will unlock the trophy / achievement.
