Arcane Ley Lines [General, Class, Magical, Arcane, Optional Rule]
Your arcane power can be used to attune to ley lines.
Benefit: You can attune to ley lines, allowing you to draw upon their power in conjunction with your arcane spells. Depending on the distance you are from the ley line, it can take as little as 1 round or as long as an hour to attune to it.
Normal: Characters cannot attune to ley lines without knowing exactly where they are.
