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 does not spawn on her own and requires the player to summon her with the Mutated Scorpion. She must be summoned in the Desert or Underground Desert. When summoning Wasteland, a Sandstorm will start.
 * Wasteland can also be spawned on the beach.

Behavior
Wasteland primarily behaves like a zombie enemy, chasing the player and jumping over obstacles. She can also follows the player if they get too far, burrowing up from under them. She does not enrage outside the desert, only requiring it to be spawned.

Attacks

 * Wasteland shoots a burst of stingers at the player.
 * Wasteland lays Eggs that eventually hatch into Mutated Scorpions.
 * Occasionally, she will jump and stay mid-air, shooting a barrage of stingers around herself before falling.
 * She also occasionally creates Sand Tornadoes, similar to Sand Elemental's Ancient Storms.
 * Wasteland digs into the ground, disappearing for a couple of seconds while sand geysers appear on the ground. 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 Dryad is within 50 tiles of her, Wasteland becomes invincible. The Dryad will then float above Wasteland, with the words "Wait! Stop!" and "I can handle this!" appearing above her head. She will then fire a burst of green energy at Wasteland and the scorpion will dig 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
