The Flask of Ichor is a Hardmode flask crafted at an Imbuing Station. While under the influence of a Flask of Ichor, melee and whip attacks will inflict the Ichor Debuff for 10 to 19 seconds, decreasing the defense of enemies by 15 / 20, therefore increasing the damage of the player's weapon by 7-8 / 10.

It will make the weapon glow when swung. If used with yoyos, it can be a good lighting source in dark areas.

This item does not apply the debuff in PvP scenarios.
