Desert Spirit

The Desert Spirit is a Hardmode enemy that can be found in Corrupted or Crimson Underground Desert biomes. A purple version of the Desert Spirit is found in Corrupt Underground Deserts while an orange version is found in Crimson Underground Deserts. However, if you perhaps cannot find the Underground Desert to be corrupted by either the Corrupted or the Crimson, you can manually make an area by using the Clentaminator with red or purple solution which is sold by the Steampunker.

Desert Spirits have an attack pattern that is unique compared to most enemies. Upon appearing near a player, they will cast a single, colored projectile that attempts to home in on the nearest player, passing through blocks and slowly gaining velocity. After a certain amount of time, it will explode. If the Desert Spirit is not attacked or killed shortly thereafter, it will cast five more of these projectiles in rapid succession. Similar to other casters, it will then teleport to a different location and repeat the process. It should be noted that the projectiles themselves do not deal any damage, but their explosions do.
