A player throwing a Toxic Flask.

The Toxic Flask is a Hardmode, post-Plantera magic weapon that has a 2.5*1/40 (2.5%) / 4.94*79/1600 (4.94%) / 3.75*3/80 (3.75%) chance to be dropped by Dr. Man Fly 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 is similar to the Inferno Fork, with its lingering projectiles and low velocity. While the Flask can potentially deal more damage, it has a higher mana cost and very limited vertical range.
  • While the Toxic Flask excels against crowds of enemies, it is usually less effective against single resilient enemies like bosses.
  • Since its toxic clouds can go through blocks, it can be used as an effective tool against enemies that can travel through blocks like worms, Wraiths, Deadly Spheres, or Reapers.
  • 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.


  • The Toxic Flask, Molotov Cocktail, and the Ale Tosser are the only weapons to feature a thrown bottle/glass projectile.
    • It is the only magic weapon to have this property.
  • Being a magic weapon, despite having "Flask" in its name, it is in no way related to the buff-granting Flasks and share no other similarities.
