First Fractal

The First Fractal is an unobtainable melee weapon that was originally supposed to be the new endgame sword for 1.4.0.1, but the concept was discarded during development. Its place is now taken by Zenith, though this item is still in Terraria's code. It strongly resembles the Terra Blade.

Using the weapon summons projectiles that resemble copies of the player (with all dyes removed) holding one of 15 different sprite variations of the sword in a flying barrage of attacks that follow the cursor. When there are enemies nearby, the weapon automatically targets them instead, ignoring the cursor position.

It cannot be reforged in-game. Using inventory editors, its best modifier is Unreal, since size bonuses have no impact on the projectile.

Trivia

 * According to Re-Logic, the First Fractal was not made obtainable because "it wasn't ready yet". Yoraiz0r stated that "as a melee weapon it did not feel melee, endgame, or clean enough. The player silhouettes ended up being confusing to some because they're dependent on the player's looks, and there was not a good enough clear line of action."
 * Its statistics are near-identical to Zenith, the only exception being use time: The Zenith has a use time of, while the First Fractal has a use time of.
 * The character does not swing the sword. Rather, the character's hand moves as if it were using a yoyo or similar animated projectile weapon.
 * The First Fractal's name is similar to one of the code names used for the Zenith during development, Final Fractal.
 * It is one of the only few unobtainable items that can be researched in Journey Mode, another being the Bone Block.
 * First Fractal was also a name for a discarded weapon concept that was developed for 1.3.0.1. The weapon would have been a sword counterpart to the Last Prism.
 * The name of the weapon in-game is displayed as ItemName.FirstFractal.
 * One of the First Fractal's projectiles simply appears to be a Terra Blade with an elongated blade, using a slightly different color palette than the rest of the projectiles.
