I personally like this part of the game. its like theorycrafting a deck in a card game. Except this time you playing against exactly what you build to counter.
The Lyuda strong point is landing multiple crits due to the bullet splitting up. so the crit spots in his chest and arms (after he attacks) really do a lot.
Since you playing Amara getting anointment really changes the game for her. I would recommend the cutsman, and getting close to the edge after you stop sliding. other things also work with the unforgiven crit swap, like the scourge or red line.
Red line you need to shoot in his crit while keeping 1 in your magazine so the stickies don’t start exploding right away and then swap.
I have even seen Epicenter with unforgiven kill grave warden kill in a minute and half. landing the grenade in his giant crit spots in his chest and arms. A little tricky landing it in his chest.
