I've run it off and on for 3 months:
120.0 Magery
120.0 Evaluating Intelligence
120.0 Resisting Spells
120.0 Mysticism
120.0 Focus
060.0 Necromancy
100.0 Spirit Speak
I lose out on wither, but at 60 necro I'm still no fail for corpse skin, wraith, evil omen, pain spike, blood oath.
The gm ss gives my pain spike enough pop, better timers for corpse/oath/omen, allows me to see the dead, and more mana leeched off of mobs.
It's very versatile in the field, and quite fun with all of the options. The only thing I don't like about it is I have to run a slightly inferior suit compared to what I generally like to run on this temp to acquire full "pvp" dci (70 dci).
I shelved the temp 2 days ago (again) so I could run my newly created fandango most uber sweet shin music suit on the planet (for a mage anyway).
