The brew command allows clerics to attempt to create potions.
Brewing a potion of a specific spell requires several things. First,
the spell must be known by the cleric, and it must be a spell that is allowed
to be brewed. Generally, most non-offensive spells are brewable.
There is a monetary cost, a mana cost, and component requirements for brewing
as well. Specifics vary from spell to spell. Some components
are harder to find than others.
Potions do not last forever, they will evaporate eventually.
Syntax:
brew <spell>
