Terraprisma

The Terraprisma is a Hardmode, post-Plantera summon weapon. It spawns a detached copy of itself that rapidly attacks nearby enemies. It is a guaranteed drop from the Empress of Light when all damage dealt to the Empress occurs during the day.

Tips

 * Like the Blade Staff and Sanguine Staff, the Terraprisma's precise movement, tracking and fixed idle position make it an ideal choice for assisting the player with faster bosses and for crowd control.
 * If the player's back is against a wall, door, or other solid block, the Terraprisma will phase through the solid block, attacking any enemies within range.
 * As it will always attack the enemy closest to the player, the user should always stay close to the intended target since marked enemies (via a whip or with the Terraprisma) will not be prioritized.
 * It is the best summon weapon in Terraria in terms of . A disadvantage, however, is its short range.
 * Because the Terraprisma does not move through blocks, while arguably the best/highest damage summon weapon available, some players might opt for minions that ignore blocks altogether, such as Xeno Staff's UFO's. This is especially useful when AFK farming, specifically in the Dungeon, as enemies will often teleport in and attack through blocks.

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.
 * Just like the Eventide, the Terraprisma seems to be based off of the Empress of Light's Ethereal Lance.
 * Despite the tooltip, 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-summoning 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.
 * When multiple minions are summoned, their pattern actually forms a helix. This is only visible with very large numbers of minions.
