Interesting thanks for the tips, I am only just at the car factory trying to sort out the raiders, and I have died about four times just on that, I am at level 6, seems to level up quite quick but I still haven't got into the perks yet.
Character start tip. Luck 5 - Intelligence 1. Unlock the "Idiot Savant" perk and pump points into Endurance & Perception. When maxed,progress the story mission until the Prydwen arrives & repeat the "Learning Curve" mission by killing the scribe from the air (youtube video available)
Important that you stack points without using them for maximising intelligence effectively.
Have fun!
