Eternity being used against a Super Dummy, with nearby Target Dummies to show its damaging ability. Notice that the flower-shaped beams around the Super Dummy deal damage to the Target Dummy nearby, but the infinity beam, orbiting crystals, and explosion only deal damage to the Super Dummy.

Eternity is a craftable post-Moon Lord developer spell tome. When used, it will create a large circle, which inside will have five crystals, a beam, and a group of projectiles that create a flower shape while traveling, all of which will be centered around a nearby enemy. The beam will travel in an infinity shape. The crystals will circle the targeted enemy. The flower-shaped projectiles will also harm nearby enemies. If the attack button is held, the beam's path will slowly grow in size as the beam changes to a darker blue color. Eventually, if the attack is held for long enough, the beam will disappear and the crystal circle will collapse in on the target, causing massive flower-shaped explosions that inflict massive damage.

Its best modifier is Demonic, as it does not have any knockback and thus cannot get modifiers that affect it.

  • Without an active target nearby, the tome does not perform any of the attacks when used.
  • Each time the infinity beam completes a cycle, it deals triple of the weapon's base damage only on the target. Otherwise, it deals no damage.
  • The crystals deal 8400 base magic damage upon collision.
  • The phrase in the tooltip "There's pictures of ponies in the book" alternates between lavender (#9C6CFB ●) and pink (#FF6CFB ●) colors.


  • The weapon's Beam projectile path follows the mathematical sign Infinity (∞), which fits with the weapon's 'Endless' theme.
    • The infinity sign (among other 8 and ∞ shaped curves) is a shape called a Lemniscate.
  • The tooltip on how the book has pictures of ponies in it is a reference to My Little Pony: Friendship Is Magic, a show the dedicatee is a fan of.
    • The Unicorn Horns in the recipe reference this as well.
  • This weapon actually has a unique rarity, but is referred to here as Hot Pink for consistency between weapons.
    • This unique rarity alternates between grey (#BCC0C1 ●), purple (#9D64B7 ●), orange (#F9A64D ●), pink (#FF69EA ●), sky blue (#43CCDB ●), yellow (#F9F563 ●), and pale purple (#ECA8F7 ●).
      • These colors are references to the main cast of My Little Pony: Friendship Is Magic: Rarity, Twilight Sparkle, Applejack, Pinkie Pie, Rainbow Dash, Fluttershy, and Starlight Glimmer, respectively.
