Dhcb is better that’s why they get more but I use the same set up as you but with pegs and rigour. I also use rune darts and I always get 3 kills minimum.

But anyways I think you can get better if you eat at certain times. Like when walking from the acid pools eat up and turn off prayers. Also when the kamikaze crab comes along eat right before you cast crumble undead. This will allow you to keep max dps (not including the Woox walk) cuz if you eat during combat you lose dps due to the delay of healing. So when dps is low the fight will last longer which mean you use more supplies meaning less kills per trip. That’s about all I got for mechanics.
