Violet Potion

Violet Potions raise the strength of the consumer to 25 for a full 24 hours. However, during this, the constution and dexterity of the user are lowered to 3. It can be consumed by all classes. This item appears in Baldur's Gate and Baldur's Gate: Enhanced Edition. In both games, this potion can be bought from a merchant in one tent of the Carnival. The player has one chance to buy one potion. The same merchant also sells the Red Potion.

In-game description
"This is one of the oddest potions you have ever examined. Once drank, this mixture causes one's muscles to immediately bulge to completely inhuman proportions, titan like actually, while dexterity and constitution are both reduced essentially to that of a slug. The effect lasts for a full 24 hours, so think carefully before quaffing this suspect drink."
