okay, i personally use this method.
start with alching materials, a mud staff, fire runes, nature runes, and soul runes.
go to the skeletons by the wilderness ditch in edgeville and get one to stand by the ditch. make it where you can only see the combat spells and misc. spells. line up your screen so the Stun spell is right next to the skeleton. start stunning the skeleton, and if you are fast enough and can get your timing down, click the alch button and click your item, then repeat. the best way is to just keep clicking the pattern untill you find a steady pace.
its like cursing and alching at the same time.
EDIT: the post above me is talking about the superheat item spell
