Terraprisma



The Terraprisma is an aerial Hardmode post-Plantera summon weapon. It spawns a detached copy of itself that rapidly slashes and stabs at nearby enemies. It is dropped from the Empress of Light only when all damage dealt to the Empress occurs during the daytime when she is enraged and all her attacks instantly kill the player.
