I suggest using:
5 Violet Archon Shards with melee critical damage since Khoras [Whipclaw] scales with that. This will hugely improve your damage potential.

ABILITIES:
ABILITY STRENGTH for Nourish and helps with early [Whipclaw] tremendously
OR
Lycath's [Hunt] for more health orbs, to give sustain with [Equilibrium] (Instead of [Primed Flow] or [Energy Nexus]) (Also companion mod increases amount of health give 60 more health). or you can use Dispensary. (Basically my old build)

Keep in mind that [Whipclaw] range caps out at 200% ability range (10m), however I still build more to improve the range of 2 and 4. But swapping [Augur Reach] or [Cunning Drift] for mods suggested below (or any other you fancy) could benefit you, but this is a personal preference (for exilus [Power Drift] could help your Dispensary drop more pickups)

MODS:
We now use more ability strength for Nourish
Energy Nexus for energy sustain

Stretch/Pilfering Strangedome is option slots. I suggest using: [Fleeting Expertise] if you don't care about Strangedome for defending (would still keep the augment though if you want loot). [Rolling Guard] could also be an option. [Streamline] would be a nice alternative too.
[Augur Reach] + [Brief Respite] is a good option for constant shield regains, the shielding is also useful for shield gating.
(forma Accumlation Whipclawn/Pilfering Strangedome for space)

The reason we don't use ability strength is that [Accumulating Whipclaw] has diminishing returns on ability strength (for example, 100% strength would be 300 base damage and 1350 damage with all Accumulating stacks, 200% strength would then result in 600 damage but only 1650 Accumulating damage with all stacks (this is just an example, with my build you can damage MILLIONS, this just shows how strength doesn't really benefit the damage outcome.

WEAPONS:
Dexterity Arcane on primary of your choosing
[Epitaph] Primer to make Lycath's [Hunt] work Epitaph Primer

For Whipclaw you want a stat stick as melee. Only: Damage, Aura Mods, Physical Damage, Elemental Damage, Blood Rush/[Weeping Wounds] and Gladiator Set (not other condition mods). Critical Chance, Critical Damage, Status Chance, Combo Counter, Weapon Augments and Rivens.
[Khora] Stat Stick and guide: Khora Stat Stick
If you have access to incarnon weapons, the Incarnon [Magistar] is the new best in slot Khora Magistar

ARCANES:
Molt Augmented for more ability strength for Nourish

COMPANIONS:
[Venari Prime] MY Venari Prime Build

If using [Smeeta Kavat] then use this build Smeeta Kavat With Khora/Venari and Venari Prime With Smeeta Kavat (Only [Mystic Bond] will be wrong forma if you want to have access to either build)

FOCUS SCHOOL:
I would HIGHLY ADVISE using the Naramon focus school so you don't lose all your combo multiplier in case you need energy or there are no enemies nearby.

Enjoy! MEOW
