Guide:Obtaining a Terraprisma

The Terraprisma is an aerial Hardmode post-Plantera summon weapon. It spawns a detached copy of itself that rapidly attacks nearby enemies. It is dropped from the Empress of Light only when all damage dealt to the Empress occurs during the day. At daytime, she is enraged, which causes all of her attacks to instantly kill the player and thus increase the difficulty of the boss itself
