Far Cry Primal Right on Target trophy guide. Kill a target 50 feet away or more using an Spear. This is fairly easy and won't require you to upgrade the spear, unless you are facing off tougher enemies that appear later in the game. The spear has much a much higher projectile drop when thrown than the arrow does so you'll have to compensate by aiming higher. In this video, I am above the target so I didn't have to aim as high and let gravity do most of the work.
