How about some love for the ranger in Pathfinder?
Intelligent Guidance-Its not what you know or who you know, its what your friends know-As a swift action, you may make a monster knowledge check against one monster that is considered you favored enemy. The base DC for the check is equal to 10+CR of the monster. If you meet the DC, you may extend you favored enemy benefits to every ally in 30 feet for one round. For every five you beat the DC by, you may extend your benefits for an additional round. This check only works for one particular enemy. You must make additional checks for each enemy of a particular type you fight in a particular encounter.
