The Ion Blaster is a craftable Hardmode magic gun. It fires continuously accelerating ion blasts that have increased damage the more mana the player has in reserve. Its projectiles inflict the Brimstone Flames debuff upon hitting an enemy. The ion blast's damage is multiplied by the amount of mana the player has, further multiplied by 0.0075, and multiplied again by 0.6 if the player is under the Astral Injection buff. The percentage of the blast's size is equal to the amount of mana, meaning the player needs at least 100 mana in order for the blast to be full-sized.

Its best modifier is Mythical.

  • Because of this weapon's unique benefit from current mana, it has incredible synergy with accessories and armor that boost maximum mana and reduce mana usage. Hallowed armor is great in this regard, giving 100 max mana and reducing mana usage by 20%.


  • The Ion Blaster's design resembles the Axiom Disruptor weapon from the video game Axiom Verge.
