I'm looking to make a character who knows everything about everything. To make such a character function, I'd want to truly benefit from the knowledge he has. Which class/archetypes benefit the most from successful Knowledge checks?
I'm aware of a few ways to improve the Knowledge rolls, I'm specifically looking for Class Features that use a success to increase the character or his party's capabilities when fighting identified creatures.
When an investigator succeeds at a Knowledge check to identify a monster‘s special powers or vulnerabilities, he can expend one use of inspiration as a swift action to grant allies within 30 feet that can hear him a +4 insight bonus on attack rolls against that monster or type of monster for 1 round.
