My magic level is 99- so I'd like to think my opinion is valid For 1 level of my 99 magic I made teleport tablets in my house. It was profitable and my butler ran soft clay for me. I'm going to assume you know how to do this. Do this to make a profit (or another lunar spell that profits) until double xp weekend and then spend all the profit you made on a fast experience method, alchemizing yew long bows is one option, as is barraging rock lobsters. I don't think you'll make it to 99 before/during double xp weekend but you can make a pretty big dent in it using this method I also did mage training arena enchant for a few of my levels so that's also an option. Hope this helped and good luck (:
