Antlion King

Antlion King is a pre-hardmode boss who is summoned whenever you destroy a Antlion Orb while underground in the desert or using the Sand Crown. It begins the battle by burrowing through the sand and trying to eat you. It looks like a giant Antlion, with a sand crown on it's head. If you leave the desert underground while fighting the Antlion King, he'll become enraged and turn red. While enraged, he's more powerful and every attack does slightly less damage.

Spawning
To spawn the Antlion King, you either break a Antlion Orb or use a Sand Crown while underground in the desert. There's also a 20% chance for him to spawn naturally in the desert underground once the player has atleast 240 HP and has beaten one goblin army. Once you've defeated the Antlion King once, this chance goes down to 5%.
