# Potion of Gaseous Form *Potion, rare* - **Weight**: 0.5 lbs. When you drink this potion, you gain the effect of the [Gaseous Form](gaseous-form-xphb.md) spell for 1 hour (no [Concentration](conditions.md#Concentration) required) or until you end the effect as a [Bonus Action](bonus-action-xphb.md). This potion's container seems to hold fog that moves and pours like water. *Source: Dungeon Master's Guide (2024) p. 287. Available in the Free Rules (2024)*
