Jason_the_Iguana: While this is true, it's also irrelevant unless you play on persistent worlds.
The official campaigns and premium modules never give you enough levels for builds like that to become viable, and neither do 99% of downloadable modules. I can recall two or three that let you reach a level in the upper thirties... but even then you typically spend the vast majority of your time playing through the lower levels.
Aielund Saga and Sands of Fate series are two immediate examples that spring to mind which are well known and often played.
Jason_the_Iguana: Plus it's pretty counter-intuitive that the prestige classes in NWN that are supposedly for spellcasters are actually only good for fighters.
Well, as I mentioned, it's still good for a spellcaster for a level 40 campaign/world, but yes, it is a bit silly. Same goes for RDD (though that's *only* good for melee classes). But that's different from saying "it's a very poor prestige class." If anything it's one of the prestige classes that is considered overpowered and nerfed in some form.
pi4t: Thanks for the answers! I only plan to take a 1 level dip in the class, for the natural AC bonus. I think that's worth losing one caster level over, given that I still maintain full spellslot progression.
It's not. The 2 AC won't matter unless you're trying to wear full plate with (Auto) Still Spell. Either invest fully in the prestige class in the Epic Levels or don't bother, it's worthless pre-epic for a caster. Only tank types should be possibly using it pre-epic.
Darvin: Given that most campaigns
end around level 15, a warning about wizard 5 / pale master 10 is important.
Except you didn't just warn him about Wizard 5/PM 10 (which I agree with), you said it was a "very poor" prestige class. In fact, it's one of the most powerful prestige classes...but only at high levels.
Darvin: Personally I don't think the caster level loss is worth it, particularly at low levels where 1 round/level spells are painfully short-lived and 1 extra damage die is a pretty big boost, but keeping the sacrifice to 1 level is manageable.
Yeah, 2 AC and 2 HP isn't worth it.
