The War Javelin is a javelin-type rangedweapon which knocks back all enemies in its path and can even be used to teleport after being thrown. This item is exclusive to the Rise of the Giant DLC.
The War Javelin can be found at the end of an obstacle course in the Cavern, next to the exit to the Guardian's Haven.
Notes[]
If the Javelin is placed in the backpack, and the mutation Acrobatipack is applied, the javelin can be thrown multiple times without being collected or returned. The teleporting function of the Javelin is also ignored.
