Great elixir

A great elixir was a powerful and dangerously unpredictable solution that was just as lethal as it was rewarding. The legend of this potion was one of the most famous examples of the magic of Halruaa.

Appearance
The elixir itself was a twinkling and translucent aquamarine liquid that always appeared to be in swirling motion.

History
The first version of a great elixir was most likely concocted in ancient Netheril. The formula of its creation was long lost since that time, although specimens appeared periodically.

Possible effects
The effect of drinking the elixir was completely random. It could have one, or a combination of, the following effects on the imbiber:
 * Instant death;
 * Feeblemindedness, as per the spell;
 * An infection of mindfire;
 * Permanent blindness;
 * Uncontrolled, daily shapechanges, as per the spell;
 * Affliction of lycanthropy;
 * Gain or loss of intelligence, charm, heartiness, strength, etc.; and
 * Gain of abilities that mimicked the spells mage armor, alter self, detect magic, detect thoughts, feather fall, hold person, invisibility, pass without trace, spider climb, water breathing, ethereal jaunt or greater spell immunity.
