It's mentioned in a few spots that ley lines can intersect in places, but it's never mentioned if you can attune to (and gain the benefit of) multiple ley lines at once. Is there a rule for this, or is it a hard cap of one ley line at a time?

No answers?
Remind me what book the ley line rules are in and I'll look it up for you.

Rules are from Occult Adventures apparently.
They don't mention intersecting ley lines at all though.
I would treat it as two untyped bonuses from the same source, so they wouldn't stack.
A generous GM might give you an additional +1 caster level over the higher of the let lines (max 5).
For example if a level 5, 10, and 15 ley line intersected each other in the same place, you would get a +4 CL bonus, +1 for the intersection (total +5).
Just an idea for a house rule.
