True, that works as well, but you need to spread your stats for warlocks to be efficient between int, wis and cha, which lowers your dex and con. Also you do not get bonus feat each 5th level and no raven familiar (+2 initiative).
As a wizard (stygian human) you can start the game with str 6 /dex 18/ con17/ int 20 / wis 8/ cha 8.
With these stats and the initiative feats you usually start every combat first (all 6 chars rofl) and by the time enemy gets to act usually they are cced or dead.
High dex gives more initiative.
High int gives more spell slots and a better DC.
High constition gives you 9 hp per lvl which is super beefy for a caster.
Low str, wis and cha will ruin your saves, but hey, best defense is a good offense anyway.
Only thing that can put a dent in your plan is enemy getting a suprise round (thats where high constitution comes into play, you have the hp to bear the brunt of it) and spell resistance, but 2x spell pen feats, spells that ignore SR like empowered maximised ice lance (with true strike cast as move action beforehand for a sure hit), 6 TIMES, will wreck anything.
Another important fact is the magic missile spell. It might not seem like much, but a red wiz at lvl 5 can dish out empowered magic missiles, which with all the feats do 4-7dmg each (and when empowered 6-10) and are long range. At lvl 13 you fire off 7 of them. On lvl 15 you can transform and get 50% more force dmg which further upps the damage. Its a awesome spell that is great for bursting down tough foes.
You do not need money since wizards are not gated behind gear (it is nice, tho).
If everything else fails, you still have the prismatic spells heheheheh
6 warlocks does sound interesting tho...
Interesting read.
Yes, warlock has less feats and even less spells (not much less, check "Help" in-game). Also less power-points, like 2 times less which is still Ok. Also, 3 stats (Int, Wis, Cha) to max, but i think you can skip one of them if you use wiz or psi spells that do not need saving throw. Like true strike, having high Int or low Int does nothing for such spell.
Some things:
All stats add to saves, so you cant really "lose" saves to some low stat. Unless you have low amount of stats total (races get different amount of stat points), but difference is not much.
You cant empower+maximise at same time, you need to choose (emp max magic missile you wrote).
Phoenix is +50% to energy spells. Magic missile is force spell (not cold/fire/elec/sonic/acid).
High con gives +9 hp per level? Not really, depends on roll. Most of times you wont get +9 even with 17 con.
Did you finish chapter 3? You get very limited in resting. You can probably pull it up, but need prepare from start.
