[3.5] Necromancy Wizard Optimization

[Mari01]

So I've been working on a character who is an elven focused necromancer. Her back story is that she is a snow elf raised on a glacier so I intend to draw heavily from that. My question is, what is there for a necromancy focused wizard to specialize in? I've decided I'm going to be the debuff master and battlefield controller. I've looked at all the wizard handbooks I could find and have gone over them, but I'm not sure what I could prestige into and keep that theme going. Is there a PrC that doesnt lose caster levels, but gives me that extra oomph. My feats as of now are completely open, but no flaws are allowed. Should I keep a familiar? I'm a bit lost on the arcane side of necromancy.

TL;DR Good Non-undead Necromancer Prestige Class. Any tips, tricks, criticisms are welcome as well.

Unearthed Arcana has a great section on wizard specializations and good methods for optimizing them, including necromancy. Battlefield control and debuffing, however, are better handled by other schools of magic, such as Abjuration and Transmutation. That's not to say a necromancer can't do it, I'm just concerned about effectiveness.

Lord of the Uttercold featline might be something to consider as an arcane necromancer. As for a PrC Pale master in libris mortis is 9/10 casting with various necromancer class features. If some homebrew is ok, past DMs for me have dropped the divine component of the True necromancer PrC and gave it full arcane progression which made it a great class for me.

Edit: getting the Tomb Tainted soul feat lets your uttercold spells heal you and your minions.

Check out dread necromancer base class if you aren't set on wizard its pretty nice.

If you are set on wizard be a necromancy specialist and then go straight into master specialist, you get some nice passives, from there you can go pale master (loses a CL) or archmage or incantrix or shadow adept to cap it out

That had crossed my mind. Using snowcasting to make ALL my spells have the cold descriptor and then going to town with debuffs.

What book is shadow adept in?

Also the group already has a conjurer specializing in battlefield control. I intend to back up him.

Shadow adept is in the Faerun Campaign Setting irc, its a good DC boosting PrC for necromancers.

Edit: Just checked, and its in the Fforgotten realms campaign setting AND player's guide to faerun, but the players guide shadow adept does not give save DC boosts.
