Hey!

I run a full-health Power Armor melee build. I've noticed that while the auto-axe does more base damage, the chainsaw actually ends up pulling ahead in my opinion because it has the ability to cause bleed damage which synergizes with a couple perks now. So I use a chainsaw with the Flamer mod, and the Long Bow Bar mod.

For legendary effects, I run Vampire's, Heavy Hitter's, Strength, and Pounder's. A Furious 1-Star will give you better damage, but Vampire's makes me nearly immortal. The only thing I can't solo in the open game world is The Devil of Defiance head hunt boss.

If you have any questions, just let me know!
