The spell imbues the creature touched with an extensive knowledge of the strengths and weaknesses of fey and magical beasts, improving his combat prowess against these adversaries. The spell grants him a +1 insight bonus to attack rolls, AC, and saving throws whenever he fights against fey and magical beast creatures. This bonus increases to +2 at 10th level and to +3 at 15th level, reaching a maximum of +4 at 20th level. At the time of casting, the recipient chooses one weapon that acts as a cold iron fey bane weapon for the spell’s duration. If the weapon is a nonmagical weapon, it also gains a +1 enhancement bonus.
