Fallout 4: Far Harbor - Reformation (the best ending)
The happiest ending with the most rewards is available if you choose this quest to end the main storyline in Fallout 4's Far Harbor DLC.
This branch grants the most rewards. If you tell DiMA you will keep his secret, this new branch will open up, revealing the ending with the least bloodshed. The plan is to take the Children of Atom's leader, High Confessor Tektus, and replace him with a replicant that will convince the faction to work towards peace with Far Harbor. Before you leave, DiMA will grant you with Acadia's Shield, a powerful and unique armour piece that grants +1 to agility, intelligence and endurance. It looks like a neck brace, but don't worry about it - Fallout 4 doesn't play great in third-person anyway.
Head back out into the wastes and go West to recover Martin's holotapes. When you get to a crashed VIM! Truck, go around the back and wade into the water. There's a sewer opening covered by moss that you need to walk through. Enter Martin's old hideout, pick up the holotapes, grab the mother icon and have a read of the notes lying about. Once you have everything, leave the hideout and fast travel back to Acadia.
(Speaking to DiMA here will cancel the 'An Execution' and 'What Atom Requires' sidequests if not completed.)
Now head to The Nucleus. Instead of doing odd-jobs for the Children of Atom to gain High Confessor Tektus' trust, you could just pass him the launch key and the means to take down Far Harbor's defences - just be sure to tell him you're not ready. Speak to him again, show him the recording and he'll trust you enough for you to be able to lure him to your secret meeting point. Once he's convinced, head back where you accessed DiMA's memories but, instead of going under the lasers, take a right.
If you pass a charisma check you can convince Tektus to leave for good, otherwise you have to use more permanent methods. If you do kill him, don't forget to use the prompt and stash him in the wall cavity. When the deed is done, it's time to go back to Acadia again.
As a reward DiMA will grant you 1,500 caps and the 'Protector of Acadia' perk, which bestows a massive boost to energy resistance and damage with a random chance when you have low health.
The quest, along with a bunch of other conflicting ones, is now complete. Take note of the active miscellaneous quest asking you to go talk to your replicant High Confessor, but first you'll also notice a new quest, Close to Home, is telling you to go speak to Kasumi downstairs. Go chat to her and you can convince her to stay in Acadia or return to her family - the choice is yours.
Before you report in to Kasumi's family, though, let's pay our robotic religious leader a visit. After he delivers a speech you can talk to him to get Atom's Bulwark, another unique armour piece that grants damage and energy resistance when you're feeling rad. Head back to Far Harbor and chat to Avery - be nice and she'll give you 1,600 caps. Congratulations. It's time for another boat ride.
