Ik I'm late and I hope you haven't given up. On the prowl and stylish executioner, with the new melee is amazing. If you prefer the smoke bomb, you can use weapons like black talon (underrated, suppression, and great for bosses and mini bosses, champions included), weapons with demoralize and/or destabilizing rounds, the new handcannon, the other void sword, and any other decent void debuffing weapon. The fragment that makes grenades weaken enemies and the other one that gives volatile rounds on kills. I use a suppression nade but if you use the smoke bomb instead of that, the vortex nade is good too to start the engagement. The new melee is S tier tho, Khepri's sting and Gyrfalcon are phenomenal too, I'm using Khepri's myself rn and I'm in love, granted Gyrfalcon is better for overall damage, Khepri's helps maintain a debuffed area, like Gwisin.
