Got this idea from Warcraft, to be honest, when I considered if it was possible to make a character in DnD that approximated the characteristics of a Warcraft-style lich. I was kind of surprised to learn that not only was it possible, it might even make a powerful character build for those who like the flavor. I'm not sure if there's some sort of standard format for build ideas, but I'll try my best:
Classes: Dread Necromancer/Sorcerer/Wizard (doesn't really matter) + Frost Mage (Frostburn)
Feats: Snowcasting, Frozen Magic, Energy Substitution (Cold), Lord of the Uttercold. Optional (might need flaws to get enough feats): Spell Focus (Conjuration)/Augment Summoning/Beckon The Frozen, or Tomb-Tainted Soul
I've seen build ideas for necromancers using and abusing Lord of the Uttercold before, but when I was reading through Frostburn, it struck me that the Frost Mage might synergize quite well with a necromancer. The class itself is full casting progression and adds a number of spells to your list free of charge (none of them great, but ah well), and yields miscellaneous perks, but the feature that interested me here was its capstone ability that gives you the Cold subtype. Not a full-blown type change, but adds the subtype. This makes Lord of the Uttercold start to look very interesting, especially if you've taken Tomb-Tainted Soul: you're impervious to the cold damage and are healed by the negative energy, allowing you to get in on the action along with your minions. If you have enough feats for Beckon the Frozen, it just gets better-your undead get the Cold subtype, too, letting them share in the fun.
Frost Mage also grants Piercing Cold as a bonus feat, which this setup could use with impunity if you want to for some reason-the feat description seems to state that while PC can bypass standard immunity to cold, monsters with the actual cold subtype are still immune, so you and your minions would be unaffected if you wanted to catch enemies in the spells as well.
Not sure how effective this build actually is, compared to others, but if you ever wanted to see what a WC Lich would play like in DnD, this is as close as you're likely to get.
