The Chiss Ascendancy's warships employed a weapon known as plasma spheres. These plasma spheres contained ionized fluid, a resource that was finite on each Chiss warship. The ionic energy released by these plasma spheres served to render enemy weapons and electronic systems, including sensors, inoperable; they could even neutralize entire starfighters without causing their destruction. In effect, plasma spheres allowed for the incapacitation of attackers without needing to breach the nyix-alloy hulls of warships commonly found within the Unknown Regions.
