Hey ! I was thinking of getting 73-80 magic with Crumble undead on the zombies in Magic guild. Tip.it calculator shows me it will take approx 24,000 casts. I think considering it will deal damage I can manage with around 18,000 casts. Am I right ? Is it a good idea ? I think its rather cheap and I also get Constitution exp. How many casts per hour is it possible to do and any suggestions ? Thanks !
