Syntax: quaff [potion]
Quaff is the command used to drink a potion. Potions can have several
spells, and may also be poisoned. Take care. You must hold a potion in
order to quaff it. There is a good chance an empty bottle will be left
behind after use. These empty potion bottles can be used for the brew
potion skill.
If you quaff in battle there is a good chance your potion may break. Your
dexterity greatly affects this.
