Spellweaving + magery:
This is my character. He is working on 120 wrestle, magery, meditation, EI, resist and weaving. In my opinion, this template is brilliant. Having an ogre lord while you're casting essence of wind is great for those intense spawning areas (like champs or ophidians or...) filled with low hit point baddies. Ethereal voyage can get you through a lot of troubles. Word of Death is the perfect peerless/Doom/Champ closer. But having nature's fury or essense of wind or Word of Death won't get you all the way through the battle. You need the normal magery spells to help you on your way. I, for example, couldn't dream of not casting invisibility after using essense of wind to bring all the baddies to me in order to set them on my arctic ogre lord tank. Unless you have a level 5 or 6 focus, energy vortex is still better than nature's fury. Energy field is still great for crowd control (especially against Putrifier or Lady Mel). The two skills mesh perfectly. What can be better than that?
Oh, yes...
Magery + weaving + necromancy
This is a tighter and more flexible template, having 7 skills instead of 6. Without certain pieces of gear, you're limited to having lower skills than you really want. Here is an example:
110 magery, 120 EI, 105 necromancy, 100 spirit speak, 100 weaving, 120 resist, 65 meditation.
With necromancy, specifically wraith and lich forms, meditation and mana regeneration become less of an issue. With wraith form and word of death, you can chain cast it all day long. With wraith form and essense of wind, you have a weapon that's more powerful than wraith form and wither. So in addition to all of the benifits of magery and weaving, you also get the benifits of necromancy and weaving and the benifits of necromancy and magery.
If you only plan on doing the monster fighting bit, there isn't anything wrong with dropping wrestling. You should have summons or ogres or meat-shield-friends do the damage taking for you. Besides, if you have a good mage weapon, wrestling is optional.
