The Ihan-rii created a variant of the immortal that served as a robotic sarcophagus for warriors who died honorably in battle, continuing to carry their remains into war. These shields were impractical for mass production. By 2505, immortal shields were heavily reinforced, making the immortal invulnerable to enemy attack for short periods of time. Originally, the shields only activated when struck by powerful attacks, which left immortals more vulnerable to the pinprick attacks of lesser foes. When the remaining dragoons were turned into immortals, the protoss decided to outfit them with these shields in an attempt to further preserve their most ancient and venerable warriors. Through this, these shields are incredibly dense, able to mitigate powerful impacts such as siege tank rounds or the blades of an ultralisk, through energy dissipation. Additionally, the hardened shields used by immortals are created by intertwining spectrums and wavelengths of varying intensity. Immortals are equipped with armor weave that mitigates impacts through energy dissipation. When deployed, immortals give critical support by eliminating enemy artillery and ranged attackers. These blasts can easily punch large holes in heavy plating, but their limited field of fire prevents Immortals from engaging aerial targets. They are outfitted with two twin phase disruptors as their primary attack form they give critical fire support to legions of zealots against ground targets, deployed when the protoss are faced with heavy enemy firepower. Immortals stand over twice as tall as a terran wearing CMC armor. Upon transplantation, immortals are consecrated in the name of Adun, as he was the one who best understood the meaning of self-sacrifice. Immortals are some of the most advanced hardware ever devised by the protoss. The machines repair aging tissue, destroy any foreign matter that might penetrate the cockpit (usually due to hull breaches) and regulate the pilot's heart rate, brain activity, and biological functions. Their pilots live in a sterile nutrient solution saturated with microscopic machines, which helps preserve their mangled bodies.
