Next, go to the teleportation point and teleport to "Evil Archer Camp".
After teleporting, look at the tree next to the chest. You can shoot the bag on the tree with the bow you obtained earlier to get materials. After getting the materials, don't cross the bridge; go to the left side of the bridge instead.
Slide down the stairs on the platform to the left, as we prepare to go to the platform on the opposite side.
After sliding down, go to the opposite side and look up to use the Kusarigama.
Climb up and open the chest to obtain materials.
Now find a nearby save point and teleport to the top floor of the Killing Intent Tower.
Climb up from the right side of the save point, walk under the furnace, and use the Kusarigama to grab the key above the furnace. You can also collect some Dust on the other side.
Climb up and obtain the key "Killing Intent Tower Lower Level Camp Outer Gate Key".
