Plasma Ball
this Yuuzhan Vong weapon was similar in many respects to a magma missile. A sphere of pure plasma energy, the plasma ball was one of the primary weapons of the coralskippers which were developed after the initial stages of the Yuuzhan Vong invasion of the galaxy. One of the things that made plasma balls an effective weapon was that they continued to erode the surfaces they hit against, even after the initial blast had passed. Thus, any hit from a plasma ball was potentially deadly. These weapons were fired from Yuuzhan Vong vessels by specialized volcanic cannons.
