This is great work,but Watchers only levitate like 10 feet above the ground.

Info HaloWaypoint:
OBSERVERS Promethean
SIZE: 128.6 cm
WEIGHT: 144.2 kg
Large sentinel fly Requiem, called observers, are typically deployed from the carapace armored knights their commanders to provide a strategic advantage air. Soaring high above the battlefield, observers not only heal their allies and increase the damage to the enemy, but they also can catch and bring the supplies, such as grenades, through a range of movement of gravity. Their very existence contradicts the enemy forces, which often resolve to attack directly, before managing other Forerunner units requiring immediate attention.
