If you want to keep your HP at 10 do the following:
1-11 Wind rush on dummies in lumbridge (free with an air staff)
11-19 Use weaken on random things in lumbridge
19-25/32 Use the curse spell on random things in runescape
Optional: At 25 if you want you can just buy enough varrock teleports it takes you to hit 32.
Another option, at level 1 do Imp Catcher, 875 Magic Exp. Buy the beads before hand and then turn them in right after starting the quest. Then confuse til 11, weaken til 19, and curse til 25/32.
