Lore
From Wyvern Source
Description
If you put skill points into your lore skill, you will be given Lore Points to spend on spells. You cannot learn spells unless you have enough Lore Points.
Every spell has a Lore Cost, which is how many Lore Points you must spend in order to learn the spell. The mana cost for a spell is also 10 times the Lore cost.
