Ok, after much spawning I can say that this char is the best type.... Use Evaluate Intelligence.
The reason is the EQuakes. If your just doing EQ to draw spawn, your missing way too much damage potential.
I pulled my SDI Necro/SW/Mage out of Doom to see what he could do at the champ spawn. EQ is the good stuff. I wither, EV and EQ. Having 120 SpellWeaving is nice, but having music/peace would probably help out a little more. I don't use much SpellWeaving at all.
BTW, it's possible to have the Bake + Ogre Lord at the spawn

I did it last night.
So now I'll finish up Spellweaving on my champer - then stone it off and put Eval back on him. I'll work up Magery when I get a scroll... 120 is nice to never fail EQ's.
