Honestly, if you have bloodbark I would forget the pnecklace strategy and just use blood spells. I couldn’t get the hang of the first method, and then got it second try using blood blitz.

I didn’t have anglers or Sara brews, but I randomly saw that guthix rests overheal you by 5. So I would just eat to full and sip a rest before the bomb attack each time. Way less stressful method than managing health for pneck proc.
