When the Goblet is found next to a dusty book about fear, it still contains six slugs of its cursed elixir. After examining it, it turns out to be some sort of healing potion, which in turn, however, lets the user's morale fail easily in combat.
Scratched deep into the side of this cursed goblet are the words "Taste My Fear." It is said that one can regain lost health from the dark blood that lurks within its pewter depths. This comes with a price, however, as all who drink of the blood become cursed with the fear it brings. This effect will last up to 12 hours or until dispelled.
Besides spelling the consumer wrong, in the original game's expansion Tales of the Sword Coast, the description reads "Heal embiber[sic] by 5 hit points" – the goblet has the same effect as in the Enhanced Edition, however: fully healing the imbiber.
