Theft is the defining skill of the thief and is only available to that
class. It allows items to be stolen from the inventory of monsters. No
thief is dextrous enough to steal worn/wielded equipment, even if the target
is asleep. Steal does not work at all on players. It is easier to steal
from a monster who is sleeping or cannot see you and more difficult to steal
from a monster higher level than you. If you fail in your attempt to pry an
item away from the monster, it will attack you. Gold modifiers (such as
buffs or equipment) do not affect the amount of coins stolen.
