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.



Tips

 * A good strategy for defeating the Empress of Light during the day is to build a skybridge out of Asphalt Blocks. When daytime comes, use the Hermes Boots (or one of its tinkers) and Swiftness Potions to run across the skybridge at full speed while damaging the Empress with a high damage weapon. This will allow you to easily dodge her attacks while damaging her from a safe distance. A good weapon choice would be the Chain Gun or Megashark with Chlorophyte Bullets, as dodging should be your main focus during the fight rather than worrying about aiming.
 * A disadvantage of using a skybridge is that it is possible to reach the end, forcing the player to turn around. This has a high risk of death, as the Empress of Light will easily catch up to the player. You can circumvent this by using a Rod of Discord to teleport around the Empress.

Trivia

 * Although its sprite appears to be a sword, it is actually a summon weapon. This is similar to other sword lookalikes such as the Sky Fracture, which is actually a magic weapon, and the Durendal, which is actually a whip.
 * Despite their name, the summoned minions look nothing like the Enchanted Sword item or the Enchanted Sword enemy.
 * The Terraprisma has the highest base damage of all minion summon weapons despite being obtainable pre-Golem and only having a rarity of . This is most likely due to the high difficulty of fighting the Empress of Light during the day.
 * The Terraprisma is the only minion-summoning weapon that does not have the word "staff" in its name.
 * The way the sword attacks, pursues, and follows could be a reference to the Sword Familiar found in the game Castlevania: Symphony of the Night.
