The Imbuing Station is a crafting station used to craft Flasks. Flasks temporarily "imbue" melee weapons with the ability to inflict a bonus debuff on enemies (with the exception of the Flask of Party, which only causes visual effects). Only one Flask can be in effect at any given time, and using another will cancel the last. Flasks affect all weapons that inflict melee damage, including Boomerangs and projectile melee weapons. The Imbuing Station is purchased from the Witch Doctor.
While the Imbuing Station is available for purchase before Hardmode, most Flasks require Hardmode ingredients. Only the Flask of Poison, Flask of Party, and Flask of Fire will be available before Hardmode.
