Ok so here is my revised character now.
Human 1 Fighter / 4 Wizard (Necromancer) (prohibited schools evocation/enchantment)
Cool. One munchkin trick is to take Ranger 1 instead of Fighter 1 at 1st level. You get a lot of bonus skill points, and you get a FAR better skill list to spend you (massive) Int bonus skill points in. The price? Heavy armor and 2 hp. Oh, and you can use wands of all Ranger spells, including
cure light wounds, which can be very helpful.
For your one "Favored Enemy", pick Undead: it's not that you particularly hate them, it's more like you know them really well from extensive (practical) study, so you're good at both making and taking them down.
Str 18
Dex 12
Con 12
Int 16 +1 at level 4 (will probably continue to add stat points here)
Wis 10
Cha 10
It kills me to see a PC with a high Strength and no Power Attack, and that goes triple if the PC has access to
true strike. There's no other use for a high Strength. IMHO it might be better to go with a high Dexterity + Weapon Finesse (which will work with all your Conjuration spells + your PrC touch attacks).
Weapons: Scythe for tripping or
Scimitar + Shield + Keen Weapon spell for extra AC and crits
Armor: for role playing purposes I'm saying my character has undead armor
that acts as a normal chain mail +4 AC basically
If you're open to dropping the scythe, you could benefit greatly by using Dex + Weapon Finesse.
Feats:
Weapon Expertise
Improved Trip
Extend Spell
Combat Casting - Still looking for a replacement for this, although
nothing seems especially appealing. Ideas?
Most likely Spontaneous Divination for wizard bonus feat next level.
You can't have Weapon Expertise with only one level of Fighter.
Combat Casting sucks. Instead, take Skill Focus (Concentration) for a +3 bonus to every check, instead of a +4 bonus to a few checks.
Spells:
1st level:
Chill Touch
Mage Armor
True Strike
Kelgore's Firebolt
Enlarge Person
Expeditious Retreat
Blade of Blood
Benign Transposition
2nd level:
Command Undead
Bulls Strength
Web
Bonefiddle
Kelgore's Grave Mist
I highly recommend
mirror image as a defensive buff, but otherwise, good stuff. Maybe you can buy it as a scroll?
You don't need
mage armor if you're going to wear chainmail. You don't need
true strike if you can't Power Attack -- and even if you could, it won't be great until you can Power Attack for -5 or more.
You
do need a ranged attack option. Maybe buy a wand of
acid orb (750 gp).
