Aeon's Eternity is a beam-firing sword in the Exxo Avalon source mod. It does 39 damage, has autoswing, and has a fast speed.


To craft Aeon's Eternity, bring 1 Desert Long Sword, 1 Ice Blade, 1 Rhodium Greatsword OR 1 Osmium Greatsword, and 1 Starfury to a Demon Altar.


Aeon's Eternity, with the addition of a Broken Hero Sword, can be forged into True Aeon's Eternity. The True Aeon's Eternity can be used with True Excalibur to create the Terra Blade, because True Aeon's Eternity is an alternative to True Night's Edge.


  • Like Night's Edge, the Aeon's Eternity is a union of four swords representing biomes: Ice, Desert, Underground, and Space.
  • Aeon's Eternity is an extremely powerful sword, lasting all the way into hardmode, and doesn't need to be upgraded until one of the mechs have been defeated. Baum used it in his Exxo playthrough.
