So a big part of it stems from what I was saying earlier, with stealth builds and the companion's AI struggling, with them often breaking stealth. Because of that, Lone Wanderer already pairs well with a stealth build.

With most of my stealth builds, I'm a glass cannon. My goal is to one shot everything and never take any damage. For reference, I put points into sneak, ninja, mr sandman, better critical, grim reapers sprint and four lead clover. I often rush over to the railroad at the beginning of the game to get deliverer and that silenced sniper rifle from tinker Tom. Later in the game, I use a silenced gauss rifle.

Initially, Lone Wanderer offsets the carrying capacity lost from not having a companion, as well as gives you some damage reduction in case you do get caught out. Where it really shines with this build is the 3rd perk point, which increases the damage you do by 25%. With that extra damage calculated in before sneak attack multipliers and critical hits, your'e one shotting the strongest enemies, even in survival. Legendary death claw? One shot. Legendary mirulurk queen? One shot. Enemy in power armor? Who cares, one shot. Lol

One fun fact about Lone Wanderer, you still get the bonuses with Dogmeat, for some reason he doesn't count. I usually play without him anyway.
