I would like to add a 2014 update as this is quite an old thread now.
Firstly, if you are raising resist with magery (by far the best method) then you need to raise Eval Int to 100 by macroing first because this will make resist rise faster.
Secondly, whether doing resist or not, get 100 meditation (or close to 100) first, using the liquor method in the Wiki here. If you take it to 90, you will probably GM it while running your magery macro but, frankly, meditation is pretty easy using the liquor method and 100 meditation will make your magery gains more efficient with less time failing meditation and waiting for mana. Not beer, as you need to drink way more of that, buy liquor.
Third, I believe the info here on lightning/e-bolt is inaccurate. I've done magery on a few toons now and you should switch to e-bolt at about 59-60 because the gains in magery and resist fizzle out from lightning way before 62 or whatever was mentioned. You will fail more casting e-bolt, but you will notice a jump in gains when you switch at 59 ish.
Using this method you will likely end up with about 80+ resist. I normally switch to 8th circle when near to GM magery (like 98) and EV stuff like demons which raises magery quicker and also brings in a good amount of cash and gets you some fame/karma. Then go back and GM resist with Flamestrike at night when you have the time. It takes a lot of Flamestrikes to GM resist and I expect like me, you want to actually enjoy the game
Edit: Lastly, I wanted to add the importance of
holding as little reagents as possible and using a restock agent to do this whether or not you are in the bank or in your home. It is no hardship at all this way and you protect your investment from mistakes. For example, even though I was in my tower last year macroing in what one might expect to be complete safety, a frenzied that one of the macroers was sitting on went wild during the early hours of the morning and killed all the macroers
Had they all been holding reagents or bandaids or whatever, it would have been a very expensive lesson! So rule number one: ALWAYS use an agent and depending on your macro never hold more than say 10 of each reagent. Don't carry anything that you would not just put on the ground at a bank and walk away from. Just not worth the risk.
