Toxic Flask

The Toxic Flask is a Hardmode, post-Plantera magic weapon that has a 2.5% / 3.75% (1/40 / 3/80) chance to be dropped by Dr. ManFly during the Solar Eclipse event. It throws a flask with low velocity and a heavy arc that explodes on impact and creates a spread of small toxic clouds that constantly damage enemies, even through blocks. The clouds last for one to two seconds.

Its best Modifier is Mythical.


  • The Toxic Flask has the potential to be an extremely powerful weapon for a wide variety of purposes. Depending on the situation, the DPS from the toxic cloud can outweigh that of the Inferno Fork, the Shadowbeam Staff, and most other Dungeon-tier weapons. Unless you have trouble supporting the high mana cost, it’s one of the best choices considering how it’s available shortly after Plantera.
  • It’s a great weapon for crowd control, but not quite so useful for bosses.
  • Since its toxic clouds can enter blocks, it can hit burrowing enemies like Diggers, and other enemies that can travel through blocks like Wraiths.
  • A single cloud will instantly disappear each time the weapon damages an enemy, which may or may not limit effectiveness depending on how many enemies are within the spread.
