The use of power suits stretches back to before the Discord. Ornate in design, each suit is an individual work of art reverently crafted by the Khalai. As is tradition, every warrior must undergo rigorous training and trials before they are allowed to don the battlegear of their station. The suit consists of a series of overlapping segmented shells providing flexibility and protection. The throat and back are left bare to allow for full movement. A zealot wearing a power suit stands about a head taller than a terran wearing CMC armor.
The suit is outfitted with a personal plasma shield generator, a vital signs monitor, and navigation tools. Intelligent servos provide compression to reduce bleeding. The suit may also be fitted with a crystalline respirator that is attached to the suit's collar.
At the end of a power suit's construction, psionically calibrated crystal matrices named warp stones are set on the armor's surface. High templar calibrate and infuse each one of these precious gemstones. These matrices serve as teleportation devices, and when a protoss wearing one of these suits nears death, they disappear in a flash of bright light as the user seemingly disappears to a place of safety. These mechanisms can also be activated manually.

The power suit is effective against small-arms. The suit may be configured to provide full life support in vacuum or hostile environments and nuclear/biological/chemical (NBC) shielding. A transceiver to communicate without telepathy may also be fitted.
