I would also like to think it would have some form of dark based raise spell
"Scratches head"
....

How on earth would this work or even make sense, The closest thing i can think of when i saw this is a spell which the name has escaped me that's on tactics ogre that "raised" a living dead member to undead. This would just be a contridictry spell. as Raise is a form of holy/light magic, i guess you can make it seem like the Dark Holy spell from FFT.

What you really are saying is you want a DRK that can control undead..it simply just won't work, nothing you can give it will make it susbsational to be useful over the already exisiting jobs.

Rightfully "Paladin" is Actualy a Holy Knight, but they didn't call it that..

and as such a "necromancer" is simply just a Dark Knight/Summoner
