struggling with yama

i tried killing yama solo with mage but when i realised how much money i was burning without getting kc i switched to melee. im running emberlight/purging with bandos and max combats. i feel like i am taking so much damage in p1 and p2 i can barely practice p3. i really get screwed when i have to dodge multiple things at once. im mostly a skiller with only real pvm experience being like 300 cg kc and that feels 10x easier than this

any advice is appreciated
