Diomedes summed it up pretty well, you're asking for alot on a single template. I definitely can't fit mysticism on this template as well, but this is the best I managed...
Skill / Real / Total / Items Required
Magery / 100 / 120 / Tome of Lost Knowledge +15 & Jewelery +5
Eval / 100 / 120 / Talking To Wisps Ward Removal +5 & Jewels +15
Med / 110 / 120 / Spell Woven Britches +10
Necro / 85 / 105 / Midnight Bracers +20
Spirit Speak / 100 / 115 / Talking To Wisps Ward Removal +3 & Jewels +12
Resist / 110 / 120 / Aegis of Grace +10
Spellweaving / 115 / 115
Real skill points - 720
Total Skill points - 840 !!
It'll be expensive to put together and you'll need to find a decent ring & bracelet combo to provide the additional +5 magery, +15 eval and +12 necro but I think it's workable. I'm not sure whether the Aegis of Grace is medable or not, I've never tried. That might be a flaw in the plan...
Edit - Actually dropping aegis of the grace and replacing it with the Necro Mark of the Travesty would let you:
1) hike the resist up to 120
2) drop you're real necro skill points to 75 and spirit speak to 90
3) take spellweaving up to 120 and magery to a real of 105, meaning you don't require the additional +5 magery from jewels.
Perfect!
