Bane: A bane weapon excels against certain foes. Against a designated foe, the weapon's enhancement bonus is +2 better than its actual bonus. It also deals an extra 2d6 points of damage against the foe.
1. Does the +2 enhancement bonus give +2 to attack and damage against that enemy (like a Greatsword going to a +2 Greatsword) or is it just there for overcoming DR?
2. How do Inquisitors typically handle choosing which creature type to use Bane on? Is a Knowledge check/Detect Alignment necessary? If I'm fighting a Dragon, Fey, Animal, Undead etc. wouldn't it be fairly obvious what I'm fighting simply based on looking at the creature and thus avoiding the necessity of a check to choose the right type for Bane?
