I do not plan to PvP at all.

So far I have.

105.3 Magery (110)
100 Eval
100 Med
100 Magic Resist
90.7 Necro
78.4 scribe

I looked at Spellweaving but I dont see anything there that I would like.. So I think its down to Spirit Speak ( though I see no use for it as I only use necro for the forms , wither , corpse skin as it still lasts long enough even without SS ) or Anatomy ( for the Eval + Anat combo ). Not sure what else I could throw in there.

Any suggestions? Like Taming ( how would that work at blackrock without the critter getting killed by all the AEs? ) maybe?

If you use wither then SS is a must. I'd GM my scribe. Crafters are a great way to make money. Especially if you get a Scrappers Compendium recipe and GM scribe. There is a chance of extra mods which bumps the price up.

Also if your playing a mage I'd recommend getting your magery as high as possible. To at least 115 or 120 if you can afford. Get you eval to the same level as your magery. Thats really helpfull.

If you don't PvP, then scrap Resists. Its pointless. Your not going to get paralyzed often. And 100 Isn't worth having really. You might resist poison from a slime, but nothing more. If I was you (which I'm not, cos I'd PvP) I'd go:

120 Mage
120 Eval
110 Necro
110 SS
100 Scribe
120 Med

Or a variation of that. Maybe work poisoning into that. Then you can lay DP fields. Remember that for DP fields Magery + Poisoning = 200

You could try:
120 Mage
120 Eval
110 Necro
110 SS
100 Scribe
80 Med
80 Nox (poison)

I have had SS as high as 90 and now it is around 45 and I havent noticed a difference on any Necro spells besides the duration or Corpse Skin. I dont really even use Wither much as I just summon an EV to take out the weaker critters. From what I have noticed is that SS only seems to effect duration of some spells and summons. I havent noticed much difference with wither though but I havent really used it alot yet.

I actually enjoy having 100 resists as it brought my basw resists to 40 no matter what which was good since I dont have good armor. Now once I can afford good armor I can see why resists arent really needed ( though I would hate to get weakened and be encumbered because of no resists or lose alot of HP from it ).

Another question would be... Do the Power Scrolls count towards the skill cap? I was told they didnt but from the templates you suggest they do?
