Flow Invader

The Flow Invader is a Hardmode, post-Lunatic Cultist Enemy that spawns near and is summoned by the Stardust Pillar during the Lunar Events. When it spawns, three smaller will appear one at a time and begin orbiting it. The Flow Invader utilizes these as attacks, sending them as 1-2 high-speed projectiles towards the player. The orbiting minions will reappear over time.

Tips

 * If the Flow Invader is killed shortly after it spawns, fewer minions will be launched at the player.
 * Trying to kill this enemy somewhat on-screen will give a player enough reaction time to dodge the projectiles.

Trivia

 * Due to its shape, name, AI, and attack method, it is likely a reference to the arcade game Space Invaders.
