Raglas are the unmanned frontal weakest attack spacecraft of the Battura fleet that appears in both Star Luster and Star Ixiom. They follow simple patterns only, and can be destroyed in one shot, regardless of strength. Once they appear in your view, get them in your crosshairs quickly and blast away. Don't wait around to see if they're destroyed. They're also defeated so easily, you're better off moving on to the next enemy threat right away.
