D&D 3.5 spellcasters

[Optimystik]

Pale Master is awful, even in NWN2. The only reason you'd go into it is making some kind of gish, or picking it up post-epic. it has 5/10 casting progression, and while its capstone ability is nice (immune to criticals) you'll probably want 9th-level spells more, specifically Wail of the Banshee.'

EDIT: Sorry, I kind of skipped to the end and missed the part about you being new, so I'll put that a bit more plainly.

A Pale Master's strength is in giving wizards (or sorcerers) more physical endurance. You gain benefits like bonus hit points, armor class, and damage reduction, plus a funky touch attack with your bony arm. However, these benefits do not outweigh the crippling loss of spell slots you will have to deal with, because PMs only advance your base casting class on odd-numbered levels.

However, 1 level of Pale Master does not delay your casting progression, and grants you a natural AC bonus, so that might be much more preferable to you.
