Survival Expert

Survival Expert is a perk that gives you different rewards. You get this perk from Moira as a reward for completing The Wasteland Survival Guide sidequest.

Types
You can see what you can get from this table. The one you receive will be based on how many optional bonus objectives you've done, and your answers. Answer Moira's questions in one of five different ways to obtain one of the five different variants to this perk. "Perk itself" means, you get it by default, bonuses are the other ones on it's right.

Example: If I've done 7 optional bonus objectives and answered in an intellegent way, I'll get Smart Survival Expert, which is giving me +4% Poison and Radiation Resistance, and +4 to Medicine and Science.

It seems that you will get answers available to you based on your highest ability Scores. For example with 10 Intelligence, 9 Agility and 9 Perception you will get only Intelligence answers most of the time.(needs comfirmation)
