Created from dried mushrooms harvested from the lower slopes of the Midnight Mountains of Orv, deep under Sekamina, vayav is traditionally cut with a number of drow poisons to make a pulpy violet clump that is smoked. The overall effect gives the imbiber a sense of warmth and invincibility, while heightening both painful and pleasurable sensations. One who smokes vayav must make a DC 14 Fortitude save or take 1d4 points of Wisdom damage. A minute later he must make a second save or take 1d4 points of Wisdom and 1d4 points of Constitution damage. Each additional dose of vayav taken within a 24 hour period increases the DC to resist its effects by +1.
Vayav also affects those merely in close proximity to a smoker. Anyone who inhales vayav smoke for more than a minute must make a DC 12 Fortitude save or take a –2 penalty on all Wisdom-based checks for as long as he remains in the secondhand smoke plus an additional hour.
Both forms of exposure to vayav are highly addictive. The morning after failing a save against the effects, one must make a DC 12 Fortitude save to resist addiction. An addicted character must make a DC 16 Fortitude save every week he doesn’t use vayav to avoid taking 1d10 points of Wisdom and Constitution damage. A character who makes two of these saves in a row recovers from his addiction— remove disease or similar effects can also end addiction.
A dose of vayav costs 10 gp in the Darklands, but costs 200 gp per dose on the surface.
