Didn't the OP request some degree of cost:XP ratio? If not, may I propose my own request please. I'd quite fancy 99 Smithing too, and not to deviate off the OP - but it seems to me that even the glorified Mith Bolts method incurs a loss of 400gp+ per Mithril Bar used. Surely, that type of loss is not being simply ignored.. :? ? Could anyone here, perhaps Master_Smither, provide a cost-effective method (besides Cannonballs & the Blast Furnace) which one could use to obtain 99 Smithing? I do not mind high-XP rates per hour; just a 'cheap' method to obtain 99. Thanks :P
