The Aetherflux Cannon is a craftable post-Moon Lord magic gun that is a direct upgrade to the Nano Purge, and is obtainable after Jungle Dragon, Yharon has been defeated. When used, it spins up for roughly half of a second, then it rapidly fires pairs of incredibly fast yellow lasers which travel in a double helix pattern. Each laser can pierce through one target and can go through tiles.
Its best modifier is Mythical.
- Unlike the Laser Machinegun and the Nano Purge, this weapon does not increase in fire rate over time. After the initial non-firing spin-up, it fires its lasers at a constant high speed.
- This weapon does not consume mana while spinning up, it is only consumed once it has begun firing lasers.
- The movement pattern of the lasers is a reference to the Wave Beam from the Metroid game series.
- The weapon's former name, "T1000" was likely named after the T-1000, the robotic main antagonist of the film Terminator 2: Judgment Day.
