Great build, Mason! Power Armor is the shit, I really need to do a character who LIVES in it like this!

I approve

The Gatling Laser with Charging Barrels is godly, even without a legendary effect.

This looks... BADASS! :D
My question was about the other Legendary effect - Two Shot, which shoots two bullets while still spending one ammo. I wondered if that will basically mean that you shoot 16 shells instead of 8. Or will it be 9 shells?

Did you use Lead Plating? Because as I recall, it is the only upgrade that requires 1 Armorer, all the others either require none or ranks 3-4 which you won't get until late in the game anyway.

Speaking of which, have you considered adding the armor mods you've used to the build in some sort of an equiment spread?

Rifleman does boost shotgun damage.

I thought it didn't really matter what your Endurance was for levelling? The wiki says a character starting with one and ending with ten will end up with the same bonuses as a character starting with ten, but that may not be reliable since that's the wiki...

Really nice! Been testing a power armour build myself (going in with fisticuffs and chems) and it's really fun. Did you every try out the Gauss Rifle? That thing is serious powerful with all the Mister Sandman/Ninja perks, and can become godlike if it's a Two-Shot or Instigating - far better than the Six Crank Laser Musket! My problem with thee builds that don't run Gun Nut is that the high end weapons (Gatling Laser, Missile Launcher, Gamma Gun, etc) generally aren't found in shops, and even then they're without any mods. Maybe it's just my luck, but I've always found it necessary to perk Gun Nut if I'm wanting to do some sort of heavy weapons build. Did you pick up Lorenzo's Artefact by the way? That thing would be perfect for this build, with all the perks you've got. It deals something like five types of damage with the Electric/Charge/whatever-it's-called mod, and most benefit from either Nuclear Physicist (radiation) or Demolitions Expert (explosives). Seriously, it destroys human enemies like no other (the only match I've found is an Explosive Automatic Assault Rifle, maxed out with all the best mods), and can cripple limbs in one hit! +1

Awesome stuff as ever Mason I confess I've barely touched power armour up the now, this gives me the motivation to dig into it.

What wiki says that it does not matter whether you start with 10 or start with 1 and increase Endurance to 10 - both end up with the same HP.
Endurance does affect the HP gain and it only increases with each level. The thing is, the difference between 4 and 2 Endurance is 10 hp at the start of the game and 1 hp per level which is not really a lot IMO.

When you start the game at 10 endurance and you actually do get up to level 264 you have thousands of HP to do whatever with. The biggest bane then is radiation damage as that's off a percentage and will eat away at that large health pool like a fat kid eating cake. 

pft, a gauss rifle is just ridiculous on it's own.
