This Fallout 4 Exploit / Glitch lets you repeat the same short and easy quest infinite times to farm unlimited XP (Experience Points). You can do this very early in the game when you’ve joined the Brotherhood of Steel.

It works like this:

Step 1: Get a high-damage Sniper Rifle with a long-range scope (should be 50+ damage, buy from vendors in Diamond City or Bunker Hill).

Step 2: After joining the Brotherhood of Steel travel to Prydwen (their airship headquarters) and talk to Proctor Quinlan. Choose to assist on a patrol and he gives you the quest “Learning Curve”. You can join the brotherhood immediately after the game starts. Do the following:
– Go to Cambridge Police Station OR just follow the main story. Either way triggers the “Reveille” and “Fire Support” Quests. Now follow the Brotherhood’s quest line until they make you a member. Then complete their “Tour of Duty” quest where you will meet everyone on the airship.

Step 3: After activating the quest, go to the deck of the airship. Make sure you are on Very Easy difficulty. Instead of doing the quest the normal way you can shoot the Brotherhood ally you are supposed to protect right from the airship and it will conclude the quest. He dies in 1-4 headshots on very easy difficulty. This is the glitchy part because killing your ally immediately ends the quest and lets you get the reward for the quest anyway. Make sure you crouch and are “hidden” before firing a shot, otherwise the brotherhood will attack you.

Step 4: Again, wait until you are “hidden” before taking a single step. Otherwise the guards will kill you (as you’ve just killed one of their guys down below).

Step 5: Return to the quest giver for your XP. He will will give you the exact same quest again, repeat as often as you want.

Each run takes about 90 seconds with loading times if you can kill the target in one hit (use strong .50 caliber sniper rifle). Each run gave me 419XP for completing the quest + 42XP for killing the target. That’s 461XP in 90 seconds or 3073XP in 10 minutes if all goes perfectly.
My Intelligence was at 11 which is why I got some bonus XP. But even with less Intelligence, you can easily score around 2500XP in 10 minutes.

With this method you will be level 50 in no time and unlock the „Legend Of The Wastes“ trophy or achievement.
