Wasteland

Wasteland is a pre-Hardmode boss that can be fought in the Desert after the Eye of Cthulhu has been defeated. Defeating or sparing Wasteland will remove the Scorpion Invasion effect. She has a relatively simple attack pattern, but can still pose a challenge to unprepared players.

Spawn
Wasteland can be spawned by catching and using a Mutated Scorpion in the Desert. When summoning Wasteland, a Sandstorm will start.
 * She can also be spawned at the Ocean if enough Sand Blocks are present.

Behavior
Wasteland slowly chases the player along the ground, occasionally performing jumps of various heights and burrowing underground for a short period. If the player moves too far from her, she will burrow into the ground and reemerge at their position. She does not enrage outside the desert, only requiring it to be spawned.

Attacks

 * Shoots a burst of 3 stingers at the player.
 * Every 2.5 seconds, lays Eggs that hatch into Mutated Scorpions after 1 second.
 * If 10 Mutated Scorpions are currently alive, she doesn't perform this attack.
 * This attack's timer can be interrupted by some of her other attacks.
 * Occasionally performs a boosted jump and remains mid-air before shooting a short barrage of stingers around herself.
 * Occasionally creates 3 Sand Tornadoes that disappear after 5 seconds. These are functionally identical to the Sand Elemental's Ancient Storms.
 * Periodically burrows into the ground, disappearing for a few seconds and spawning 4 sand geysers along the ground. Wasteland re-emerges from the geyser emitting green particles.
 * Wasteland cannot be damaged until she re-emerges.
 * In Awakened Mode, fires a spread of 5 acid balls in an arc, which become stationary and inflict the Acid Burn debuff on contact.

Sparing
When Wasteland is at 500 Health and the Dryad is within 50 tiles of her, Wasteland becomes invincible. The Dryad then floats above Wasteland, with the words "Wait! Stop!" and "I can handle this!" appearing above her head. She then fires a burst of green energy at Wasteland and the scorpion digs underground, dropping the loot she would normally drop on the surface before burrowing away.

Aftermath

 * Scorpion Invasion is removed from the player.

Tips

 * Building an arena with platforms can make the fight significantly easier.
 * Using Sanguine can be useful to deal with Wasteland's minions in an easier way due to Sanguine having piercing projectiles.

Trivia

 * Wasteland's theme is "Sandstorm Curtain", which was composed by Ranipla.
 * The old theme for Wasteland was "Royal Vaccination", which was also made by Ranipla.
 * If the EA Music add-on mod is not installed, Boss 1 will play instead.
 * Wasteland resembles deathstalker scorpions in various aspects, including: color patterns, behaviour towards certain predators, and their ability to jump high into the air when threatened.
 * The mod's creator, ThatOneJuicyOrange_ has confirmed that Wasteland is not intentionally based off deathstalker scorpions.
