Dragon's Breath

The dragon's breath is a brewing item that is used solely to make lingering potions.

Harvesting

Dragon's breath can be obtained by empty glass bottles on the ender dragon's breath attack while perched, or on the purple effect clouds caused by dragon fireballs.

Brewing ingredient

Dragon's breath may be added to any splash potion to upgrade it to a lingering potion, which can be used to create a lasting area effect cloud, or to craft tipped arrows.

With two or more dragon's breath in the brewing stand, after the brewing process, a glass bottle drops as an entity. However, with one dragon's breath in the brewing stand, the glass bottle is consumed and cannot be retrieved.

Trivia

If the dragon's breath is used in a crafting recipe (using a mod or a data pack), it becomes an empty bottle instead of being entirely consumed.
