The Helium Flash is a craftable post-Moon Lord wand. It fires a burning star core which bursts on impact into an enormous flaming explosion much like the Inferno Fork. The explosion ignores NPC immunity frames and inflicts the Daybroken debuff for an extended period of time. The burning star core additionally inflicts the Irradiated debuff if it strikes an enemy directly.

Its best modifier is Mythical.

  • The tooltip of this weapon references the power of real-life helium flashes. They produce as much heat as an entire galaxy for about a minute.
