Predictor

The Predictor is a Hardmode, post-Lunatic Cultist enemy that spawns around the Nebula Pillar during the Lunar Events. Its main attack is firing five Nebula piercer projectiles at the player, which travel in a straight line in a tight spread. The Predictor will not shoot if there are solid blocks in its way. It does relatively high damage, so fight it with caution, as the 5 projectiles can hit you all at once, doing extreme damage.
