"...A dried up and gluttonous husk on a constant and voracious search for its next meal."
The Desert Scourge is a Pre-Hardmodeboss. It is intended to be one of the first bosses fought by the player and is considered to be the weakest of all of the bosses added by the Calamity Mod. It is intended to be fought before the Eye of Cthulhu and after the King Slime, but can still pose a considerable challenge to new players with only basic equipment.
Desert Scourge behaves like a regular worm enemy, moving through blocks and attempting to ram the player. The Desert Scourge has 27 / 32 / 37 / 42 segments in total.
It becomes enraged if the player leaves the Desert biome, increasing its speed and acceleration by 50%.
Upon reaching 50% / 75% / 100% health, the Desert Scourge will occasionally burrow underground and roar, then rapidly lunge at the player before burrowing again from a height 37.5 tiles above the player.
This attack occurs every 9 / 7 seconds. After performing the attack, this timer resets on the apex of its lunge.
If the attack takes longer than 10 seconds, it will automatically reset to its default behavior.
When the Desert Scourge is below 75% health, striking a body segment will have a 10% chance to spawn a Dried Seeker.
There can only be up to three Dried Seekers at a time.
If the Boss Checklist Mod is installed, its unique despawn message will be "The scourge of the desert delved back into the sand."
When the Sea King, Amidias refused to partake in the forbidden ritual to awaken the Moon Lord/The Dark Lord from his slumber and imprisonment on the moon, the Jungle Tyrant King, Yharim, had the witch Calamitas evaporate all of the sea's water with fire and brimstone. This event caused the great sea worm, now known as the Desert Scourge, to go on a rampage. Deprived of its previous food source, Crab and Shark meat, it turned to devour the remains of the inhabitants of the desiccated sea kingdom. Now the sea worm itself has dried out and become a hollow shell of its former self, constantly seeking fresh meat for it to devour.
