i just beat it so i would say, start using supercharge (a move for susie) after the first heart attack, and try to stock up on cd bagels or but. juice, keep a clubs sandwich and topcake/spin cake on you just for emergency purposes, and do not underestimate the power of big shots, also, if you start running low on hp, just start defending instead of snapping for some tp and use a bunch of heal prayers after you run out of items, and if you take lets say one or two hits, dont let it stack up, use heal prayer before you run too low on hp, that has lost me multiple times.
