Nebula Floater

The Nebula Floater is a flying enemy that spawns near the Nebula Pillar during the Lunar Events. It periodically spawns eyes that float around it. Its main attack is either ramming the player, or shooting a Nebula Laser from one of its followers at you doing significant amounts of damage. It will also try to teleport around the player while firing its laser, appearing to do this more often in Expert Worlds. It is one of the enemies of the Nebula Wave that must be paid attention to. They are somewhat common and in groups can overwhelm the player. One of many recommended weapons for fighting it is the Solar Eruption as any decent crowd control weapon will do fine.
