Invincibility

Invincibility modules are a defensive equipment piece developed by the Covenant for use by infantry forces.

Design details
Invincibility generators consist of a small, handheld generator interspersed with golden lights, similar in form to the cloaking module. When activated, they provide an extremely strong energy shielding layer to the wielder, which makes them near-invulnerable to damage for a period of around ten seconds. The United Nations Space Command have been able to determine that the source of the protection offered by the module stems from a latent energy field, though to-date have had little success in reverse-engineering it.

Usage
Invincibility modules were developed by the Covenant, and prominently-used by Jiralhanae Chieftains during the Human-Covenant War.

Halo 3 and Halo 3: ODST
Invincibility appears as a piece of deployable equipment in Halo 3 and Halo 3: ODST. In both games, the equipment can near-exclusively be found in the hands of gravity hammer-wielding Jiralhanae Chieftains. When engaging the Chieftains, should they take too much damage they will activate the equipment and become temporarily invulnerable to nearly-all forms of damage. In Halo 3, if they can be killed quickly, they will drop the module and leave it open for a player to pick up; this function is removed in ODST alongside all player equipment use. The behaviour exhibited by Chieftains in ODST tends to make them overly defensive with their equipment, and they will activate it as soon as they are attacked by a heavy weapon.

Although invulnerable to most forms of damage, Brutes with invincibility activated can still be assassinated or splattered. If the player in Halo 3 has invincibility and makes an NPC Arbiter an enemy, he will still be able to kill the player in one hit.

In Halo 3: ODST, Invincibility makes Chieftains glow an aquamarine color, instead of the original white. This is because Brute's armor glows white when shot in Halo 3: ODST, so Bungie changed the color, so players could clearly see when a Chieftain activated invincibility.

Trivia
The image used for the Invincibility's activated state in the Halo Encyclopedia (2009 edition) and its 2011 reprint is in fact a screenshot of an early revision of the Z-4190 bubble shield from the Halo 3 Beta.
