I've done some preliminary checking with the DMs on the site I'll be playing, and they won't allow a vanilla Warlock to qualify for Iot7FV. (Their read of the prereqs was, "Must be able to cast 4th-level arcane spells, 2 of which must be abjuration in order to properly screw over sorcerers.")
So...I can get into it a level later, but it's going to take more work - and I need some serious help in how to seriously pimp out a wizard's save-or-suck area spell list.
[spoiler=Allowed sources - if it's not listed, I can't use it.]PHB, DMG, MM1.
All Completes except CChampion and CPsionic.
Cityscape, Dungeonscape, Frostburn, Sandstorm, Stormwrack.
Drow of the Underdark and Heroes of Battle.
Spell Compendium.
Any WotC FR source 3.5 (including dragon mag articles specifically listed as so)[/spoiler]
Race-wise, I'm limited to standard FR races (no LA+ or templates). Half-elves get a bonus feat from the skill-affinity set, which is an option since I need Skill Focus (spellcraft)...and I'd rather not play a human this time around.
I have 13 levels to play around with, total. Stats-wise, I have a 32-point which I was going to drop in as 8/16/16/16/8/10. The build stub, so far, is Wizard1/Warlock1-3/Wizard2-3/EldTheurg1-4/Iot7FV1-3 - this gives me Wizard7 and Warlock10, plus two Wardings a day.
[spoiler=feats]Skill Focus (spellcraft) (B, either from half-elf or halfling)
Scribe Scroll (B Wiz)
Spell Focus (abjuration) (1st)
Greater Spell Focus (abjuration (3rd)
Three feats open. I was considering either Improved Familiar, or Ability Focus (Warding) for a higher DC[/spoiler]
[spoiler=invocations]
Leasts:Otherworldly Whispers, Entropic Warding, and probably Eldritch Spear
Lessers:Flee the Scene, I'm grabbing. The others...Fell Flight, Eldritch Chain, Walk Unseen?[/spoiler]
[spoiler=spells]Most of the help is going to be needed here.
Spells, limited as they are, are going to have to give me some more versatility in offense (area spells via Spellblast) and some decent defenses. I'm not totally versed in the breadth of the Save-Or-X list, so don't laugh too hard.
1st:Color Spray, Shield, Grease, Benign Transposition, Hail of Stone (heh, same FRA!). Others?
2nd:Glitterdust, Mirror Image, Resist Energy, Ray of Stupidity, Shadow Spray are the only ones that I can see. Others?
3rd:Dispel Magic, Explosive Runes, Nondetection (?) Tongues, Greater Mage Armor, Anticipate Teleport, Bands of Steel, Haste/Slow, Great Thunderclap.
4th: (I won't get many of these, so I'll need to make them count)
Dimensional Anchor, Ray Deflection (these two satisfy PrC requirements); Greater Invis, Assay Spell Resistance...[/spoiler]
So...pimp my ride.
