If you expect to have a healthy income of astral, nature, or death gems, make sure you'll have access to S4D1, N5D2, or D3, respectively.

At conj6, you can cast "Ether Gate", "Contact Lammia Queen", or "Summon Spectre", respectively; all of these have random magic picks, and can be an easy way to diversify your magic.

And diverse magic = more options = winning strategy.
