Welcome to Librarium Online!
SO here is a bit of an idea. I am slightly concerned at such low points levels that the army general is going to be very exposed and you cant really get enough in, but hopefully this might work.
I guess the 'plan' is to hang back a bit, trying to keep the wraiths and vargheists out of line of sight of anything that might shoot them, and hoping to get off some invocation spells to bolster the units. Once they get close, I can unleash the full movement of the hexwraiths to go through whatever of his units I want to hurt and then use their free reform (for being light cavalry) to threaten a rear charge on his army. The vargheists can either pick off anything on the flank or also try and fly overhead, so that once he joins my army in combat I can soak up the initial charges with my skellies, hopefully neutralise his stronger units with the wight king.
The zombies can serve as a bunker for my necromancer, tucked away behind the two skeleton blocks, so that he can toss out a curse or two and soften the enemy units up whilst raising more dead for me to hold him in place.
129 Wight King
+ great weapon
+ master of the dead
230 Skeletons (hand weapon and shield) x40
+ Full command
190 Skeletons (shields) x32
+ Full command
136 Vargheists x3
150 Hexwraiths X5
45 Zombies x15
First thing i would do is bump the zombie unit up to the minimum leagal size of 20 and give them musician and standard. Its worth it for what you pay in the long run.
Second i would drop the skeleton units down to 30 strong. Yeh your not the best fighters but thats still 60 skeletons which you can raise each turn anyway.
Necomancer, keep master of the dead but dump cursed book. Give him lvl 2 as +2 to your casting is going to help, aswell as because his level adds to the number of models which get raised. If you want to give him any bound item give him book of arkhan, as this is just cheap enough to be good, and will help your skeletons out in combat if you dont roll the spell or only have one dice at the end of casting to use.
If you wanted cursed book i would be dropping the WK and taking 2 necromancers.
Sure you want a white king? If so i realy wouldnt bother with nightshroud. Not much will kill you right off with 3 wounds at T5. use magic items in the BRB and give him a 5+ ward if your desperate, then maybe see what over magic items you could use on him from there.
I might look at squeezing an extra varghiest into the unit but 3 should be ok as long as you dont loose one.
Yeah, you are right about the zombies. That is a definate change. The Wight king just seems to be to be a good cheap guy to be holding up any elite enemy heroes or regiments and stick around without dying, plus enemy heroes are going to be taking a risk engaging him in a prolonged combat when he is difficult to kill and the chance of him getting a killing blow is dangerous.
I did have another idea of just having a single well armed vampire leading, but it got too expensive to fit him and the necromancer in - what do you think of maybe a necromancer lord for the casting and a tooled up vampire for the combats (and a little magical support) It leaves less points for the troops, but I guess with a lucky invoacation or two I could have the numbers boosted.
The book was there for a purpose - if I get a two or even one dice casting of a spell then I am getting quite good value for money (especially some of those lore of shadow spells that cost upwards of 10 to cast) and the hexes are all useful for supporting my troops - I think I would prefer to be weakening my opponents to make it easier for me to hurt them (or harder for them to hurt me) then some of the augment spells in the vampire lore which, while good, are not going to do much about his retalliation.
