[Khora] has a powerful base kit due to the synergies between her abilities and the ridiculous amount of damage from Whipclaw. This build focuses more on her crowd control potential while subsuming a survivability or QoL ability.
[Venari] should be replaced if you aren't planning on using its abilities. The only options that fit would be Dispensary to give you a free Energize roll between waves or Quiver to make the team invisible after an accidentally dropped Strangledome.
Ensnare propagates when enemies are hit by Whipclaw. It's a powerful CC that we don't need to utilize a second subsumed CC ability with to abuse.
[Swift Momentum] isn't for Whipclaw. It's to increase the QoL of you and your team's melee weapons to blender enemies under CC effects. It can be replaced with any other aura of your choosing like [Corrosive Projection] against armored enemies.
[Pilfering Strangledome] is run for free additional drops but it does have weird synergy if you're running a melee build. It can be dropped for more duration.
Arcane Strike increases the DPS of your melee attacks but it can be replaced any other arcane to suit your playstyle.
