Question: With Illurien, what does knowledge devotion actually do? Asking since it just says "Knowledge devotion (Ex): At 9th level Illurien gains the benefits of Infinite knowledge as well.", which doesn't really make much sense to me.

Basically, Infinite Knowledge only gives bonuses to your allies, but at ninth level, it gives the bonuses to you as well.
