Melee Amara works. The issue with Amara and melee is that you will, guaranteed, want the Body and Mind skill, whether you’re doing actual melee or are simply using a Facepuncher as a Body and Mind delivery system.
The tree I’d recommend for pure melee is thus: here
I, personally, did not like how Phaseflare worked, so I wound up doing what’s called Cast Stab Amara, skill tree here.
With Cast-Stab, you can use Phasecast or its variants, like Tandava, to activate Phasecast 250 anoints or 100 melee anoints, and then just use a Facepuncher as a Body and Mind delivery system. A x14 Facepuncher with so little as 1 point in Infusion gives you 28 whole hits of Body and Mind, so I can typically enjoy 2-5 million x28 hits. It’s pretty much enough to destroy anything in the game.
I use a Radiation Stone Victory Rush, because I don’t have a Deathless with a +% melee passive, but Deathless with a melee passive and the urad anoint is peak damage, though I’m slaughtering everything in the game without that, so I don’t care to continue farming for said Deathless lol.
