Do Instant Enemy and Hunter's Bond work together?
Instant Enemy:
"With this spell you designate the target as your favored enemy for the remainder of its duration. Select one of your favored enemy types. For the duration of the spell, you treat the target as if it were that type of favored enemy for all purposes."
Hunter's Bond:
"This bond allows him to spend a move action to grant half his favored enemy bonus against a single target of the appropriate type to all allies within 30 feet who can see or hear him. This bonus lasts for a number of rounds equal to the ranger's Wisdom modifier (minimum 1). This bonus does not stack with any favored enemy bonuses possessed by his allies; they use whichever bonus is higher."
