Potion of Invisibility

Potions of Invisibility make the consumer invisible, but not undetectable for the other senses. The effect is the same as the second level wizard spell by the name of Invisibility. Actions related to combat will make the consumer visible once again. If these activities can be avoided, the effect will last 12 hours in-game time. This potion appears in Baldur's Gate, Baldur's Gate EE and Baldur's Gate II. In the game of Baldur's Gate, this potion is for sale at Sorcerous Sundries.
