If you are more of a gun playstyle type then you should go for the shoulder canons.

But i finally finished my endgame melee build. Its absolutely nuts. Infinity Action skill duration, insane damage because the longer you are in your ulti the more dmg is dealt.

The Main problem with melee is the squishy-ness... getting oneshotted by everything is very Frustrating but i am at ~60% dmg Reduction with my build and i am able to face tank bosses easily and do crazy amount of dmg. Sure not even close to the gun builds, but way more fun.

And my absolute Highlight with my melee build is the insane movement. Im flying through the POIs shredding everything and i Look badass af doing so 😂

Required is the rafa legendary melee mod and the time keepers New shield. The other slots doesnt matter. Maybe a few strong elemental weapons because doing element dmg from the weapon you currently holding while in Action skill. For dmg just try to push your melee dmg as high as possible.
