Joostmod/Cactuar

Cactuars are hardmode Desert enemies. They will occasionally fire a barrage of needles at the player that ignore immunity frames. When the player gets near they will begin jumping at the player. Corrupt, Crimson, and Hallowed variants always jump at the player and Hallowed variants will also occasionally fly towards the player at high speeds. When a Cactuar's health reaches half it will flee away at ludicrous speed.

Trivia

 * Cactuars are a reference to the same enemies from the Final Fantasy franchise. They have an associated vanity set as well, the Cactuar costume.
