For the glitch, see Invincibility glitch.
Invincibility is an equipment item used by Covenant Jiralhanae forces. It provides a temporary boost to the user's energy shield system, giving the user a brief period of invulnerability lasting for about 10 seconds. It is used almost exclusively by Jiralhanae Chieftains.
Invincibility generators are used almost exclusively by Jiralhanae Chieftains, specifically ones that wield Type-2 gravity hammers. When their energy shields are depleted or they are surrounded by a large number of enemies, Chieftains will typically activate their invincibility and execute a berserk charge at the nearest enemy. In this state, their shields are augmented and will deflect any damage from firearms or explosives.
It has a similar appearance to the Cloaking equipment, except that it glows a gold color, rather than a cool blue color. Its symbol on the HUD is two overlapping, intersecting ovals with a dot at the center.
The way the Invincibility works is by making a hyper-excited electron layer, basically sending plasma-armor into overdrive. The nearly solid electromagnetic layer acts to almost instantly stop, or reverse the trajectory of, anything that comes in contact with it. This means that, while invincible, the subject is virtually immune to all kinds of projectiles and explosives.
