Just listen to me, I know something!

Baffle with BS Feat 4

General Skill
Prerequisites: expert in Arcana, Lore (any one), Nature, Occultism, or Religion.

You know a thing or two, so obviously you know what is going on. When you are interacting in a manner where the skill you would be involved, you can substitute your knowledge check for a deception. diplomacy, or intimidation check instead.

Thoughts?
