Most Cost Effective Magic Level Training?

[Jwlz]

So, I've got a 56 Druid (Located in my life thread if you wanna check it out)

I'm seriously unhappy with my ml, 47...

What is THE FASTEST and MOST COST EFFECTIVE way to train my Magic Level.

Of course I'm not expecting to profit, but I wanna gain some ML's FAST!!!

Any tips?

Thanks
Jwlz.
