The feature does not explicitly say that you gain all the benefits of the enemy you choose: In fact, it says you can only use one adaptation at a time, and that each ability or feat from the favored enemies are different adaptations. However, it doesn't say anything about actions to use them, or whether you can switch to different adaptations during the 10 minute intervals.. Overall, a neat idea that is poorly written and needs an official clarification (Preferably soon because I'm about to hit level 3 :P).
