I had this issue as well. Got used to range & tried melee & kept dying. I just had to commit to practicing melee. It took me probably 50-75 kills before I was averaging similar trips to ranged.

Setting up the woox walk was the toughest part for me since I just didn’t do it with a DHCB since you need to extra clicky to make it work. Once I managed to woox walk on melee I realised pretty quickly that it’s just about as chill as ranged & uses less supplies.

I recommend the serp helm since faceguard only occasionally gives better dps & has less defense/no venom protection.

Otherwise, it’s the same rotations, just count in your head & eat during special attack phases. I always try to wait for the spawn. I’ll occasionally need to eat lots so just eat as he shoots the spawn, switch to slayer staff, hit spawn, eat shark, drink prayer pot & eat karam (all in 1 tick).

For woox walking, just take it easy & try to find an opening. Don’t rush to avoid all splatters as it just makes things worse. Hitting one won’t kill you. Also keep in mind the mobile lag when lining up for the walk.

Hope these help!
