Warp ray

The Warp Ray was a retractable artillery weapon mounted on a robotic arm 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 a Warp Ray attached to a robotic arm to unfold out of the ship. The Warp Ray then proceeded to fire prismatic beams at Blackout's fleet, destroying a full third of his ships in the ensuing barrage.

Trivia

 * The Warp Ray originated from Starcraft II: Wings of Liberty. The weapon was later renamed to "void ray".
