Potion lore is a skill used in conjunction with the brew potion skill.  Brew
potion may be used without potion lore - but potion lore is useless if you
don't know how to brew anything.  Typically, guildmasters will refuse to or
be unable to teach you potion lore before you know how to brew anything.

Potion lore is used automatically when you attempt to brew anything.  As you
become more learned in the art of potion making, you will be able to identify
the less common effects that a set of ingredients can produce.
