Promethean Watchers are found with a wide variety of weapons. The only weapon they are not found using is the Energy Gun. Promethean Watchers have the ability to pick up projectiles and throw them back at an enemy, proving useful against grenadiers. Promethean Watchers are the absolute lowest rank of Promethean, however they have the ability to, given enough supply, create other Prometheans and Forerunner combat ancilla.
