Warp ray

Warp rays were retractable artillery weapons mounted on robotic arms on the Magisters' Terrace that could fire prismatic beams.

History
During the Battle of BZPower, Malygos announced that he would unveil the latest addition to the Magisters' Terrace. On his mark, three panels on each side of the Terrace opened to allow several warp rays attached to robotic arms to unfold out of the ship. The warp rays then proceeded to fire prismatic beams at Blackout's fleet, destroying a full third of his ships in the ensuing barrage.

Trivia

 * Warp rays originated from StarCraft II: Wings of Liberty. They were later renamed to "void rays".
