[Favored Foe][1] is used on hit, and works with [Foe Slayer][2]. Does the Ranger need to hit normally first, (without using Foe Slayer), and then on future attacks they can use Foe Slayer? Or, can the Ranger use Foe Slayer to turn a miss into a hit, allowing Favored Foe on the first attack?

Thanks!
