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 minions 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. The Flow Invader will launch all of its remaining minions at the player upon death.

Tips

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

Trivia

The Flow Invader's minions are technically projectiles, with a Projectile ID of 539.
- The Flow Invader's minions are also present as an unused NPC, having a graphically identical NPC of them named Mini Flow Invader.
