The Alpha Ray's two different modes.

The Alpha Ray is a craftable post-Moon Lord magic gun with two firing modes. The left-click mode has three main parallel laser beams and also shoots laser projectiles rapidly. The right-click mode shoots a beam that splits into two like the Genisis, although lacking the scattered laser-fire. All projectiles fired from this weapon travel through blocks and all particle beams pierce indefinitely. The three particle beams deal 80% of the weapon's damage, the secondary-fire's beam deals 175% of the weapon's damage, and the additional laser projectiles deal 40% of the weapon's damage.

Its best modifier is either Masterful for mana conservation or Godly/Demonic for higher damage output. It cannot get the Mythical modifier due to its low mana cost.




  • The left-click mode's main beams deal Alpha Ray's actual listed damage while the secondary laser projectiles deal only half of it. On the other hand, right-click mode beams deal double the weapon's damage. Despite that, left-click mode actually reaches higher DPS due to faster fire rate and additional fired projectiles.


  • The Alpha Ray's sprite resembles a combination of the weapons used to craft it.
  • The Alpha Ray was implemented based on a community suggestion made by Gouvod on the mod's Terraria Forums post.
