Jhuild (firewine)

The dark reddish brew (not to be confused with the Old Empires drink called firewine) is made by the witches from grapes and fruits specially grown on plantations near the city of Urling, with various herbs added for increased potency. While it is not truly an enchanted item, its effects are certainly close.
Jhuild is generally considered to be the national drink of Rashemen. The land's berserkers are said to consume considerable quantities of firewine before going into battle, and it is said to both increase ferocity and bolster morale.
Each pint of jhuild consumed has the following effect: It increases morale level of NPCs by 1 (maximum increase of 5), decreases Wisdom by 1 (maximum decrease 5, to a minimum of 1), and adds +1 to all damage rolls - all for 2d4 hours after consumption. These effects may be avoided with a successful Con roll, but the roll must be made for each pint separately and is at a cumulative penalty of -1 for each pint consumed.
Once the 2d4 hour period has elapsed, the drinker immediately falls into a deep sleep for 3d4 hours and awakens with a throbbing head, thick tongue, and a miserable desire to crawl under a rock. This is all considered part of the price the Rashemaar pay for being the fiercest warriors in Faerûn, and no one complains (at least not much).
Firewine sells for 1 gp per pint within Rashemen and at least 15 gp per pint in other lands, with the price increasing the farther one goes from the land of the berserkers. A single bottle of jhuild, containing about two quarts, is said to have brought 100 gp at an auction in Waterdeep, for example.
