Good to see a non-uber race build with a different spin from the Eternal Undead Master:
http://nwnprc.com/index.php?topic=1400.0A couple of small bits.
Not going for Epic Spellcasting? The build ends with 22 Wis. Epic Mage Armor, Deadeye Sense and Epic Warding are must haves for serious OP cheese. All it costs is a few skill points and 1 Epic feat. Also, the S-craft skill points boost magic saves.
Corpsecrafter makes your undead minions a little stronger. Not sure if they are considered 'created' vs summoned. Worth a look.
With TWF, Div Might is a big heavy damage bonus adder w/ the right gear. I would probably go Div Shield as well and just Dual Wield. Also nice if you load up a big bad bow.
Unliving Weapon is great to blow up Undead traitors. Destruction Retribution is also something to consider.
Would go for Plant domain to get Creep Doom. Protection is meh vs Div Shield + high Cha gear. The only thing that sucks about CD is that the Undead tend to run into the CD cloud and soak up damage. Love CD + Storm of Vengeance + missile attacks.
Stop Heart is a great killing spell. You just have to stock up on Baccaran. Slay Living was pretty good, too.
I would stay away from Dev-Crit and just toolset items that give Dev-Crit as a bonus feat. Way too many feats and strength tied up in DevCrit for my taste. Div Might + high Cha gear + Deadeye Sense are a great set.
An easy way (albeit costly) to dispose of the treacherous undead was: cast Gr Timestop (Epic spell), cast Unliving Weapon on 6 different ones, cast 1-2 Fire Storms. Done deal. They would effectively blow each other up. Funny to watch.
Might go for Extra Turning over Improved Turning. They aren't usually that treacherous. ET is 6 additional OP undead summons.
Undead Mastery may (??) give you summons headroom to bring on a fair bit more firepower.
For added flexibility for a very high Wis build, consider Zen Archery to add the missile dimension into the arsenal. CD + SoV + missile attacks are serious fun. Stacks well with Div Might + Shield.
Love the build and thanks for posting.
