Ascetic harness

The Ascetic harness is an armor set used by the Sangheili Ascetics. Its role is that of inducing fear and ceremonial services.

Development and history
The Ascetic harness is utilized exclusively by the Sangheili Ascetic Corps, a group consisting of some of the most elite warriors within the Sangheili race. Only the highest-scored graduates of Sangheili military academies can be considered for placement in the Ascetics.

Helmet
Unlock: Unlock the Steppin' Razor Achievement.

The helmet appears completely sealed. Two yellowish-orange bulbs mark the location of the wearer's eyes. If you look closely enough you can see slight bulges where the jaws are. Along the jaw-line and for about fifteen centimeters (six inches) beyond, extend two silvery tusk-like protrusions similar in design to those found on stealth Brute headpieces. These tusks also look strikingly similar to a Brute Spiker's blades. Judging by the description offered in-game, the helmet-mounted blades are likely meant to further augment the wearer's already frightening appearance. The helmet also comes with a white, flexible neck piece.
 * Description: With the return of our sovereignty comes the much needed revival of the Ascetics; now more then ever our culture depends upon their resolve to help ensure stability.

Shoulder pauldron
Unlock: Unlock the Overkill Achievement.

The shoulder pauldron is made up of a quarter-circle shape with two blue lights in them and a number of indentations. The shoulder pads appear similar to those of the standard body armor worn by the COG soldiers of Gears of War.
 * Description: As the physical embodiment of ideological purity' an Ascetics' presence promotes feelings of stability and order; by example they will show each of us the true path.

Thoracic cage
Unlock: Unlock the Up Close and Personal Achievement.

Similar to the standard Combat harness. The only noticeable difference is a protrusion, shaped like the English letter I, filling what would otherwise be a gap between the right and left breastplate. This chest plate is connected to the waist armor of the Elite. The combat advantages of this is unknown, but as an ergonomic feature it would seem to be designed to better the posture of the Elite, making them stand straighter and taller than other Elite counterparts.
 * Description: The Ascetic instills confidence in those loyal to the state and fear in those who would undermine it; to that end their actions are swift and their decisions final.

Trivia

 * The body is possibly the easiest part of the armor to unlock as many players use melee attacks during games, easily getting them the Up Close and Personal achievement.
 * Even though the Ascetic Helmet comes out farther than any other Elite helmet, it still has the same hitbox as any other Elite helmet, meaning the tusks have no effect relating to gunfire. However, they stand the risk of giving your position away to keen-eyed enemy snipers if they accidentally protrude from behind a corner.
