Does anyone know if the spells the vampire lord uses are seperate from a skill tree or if they arent if they are destruction or illusion since I want to use my archer argonian vampire that only uses illusion.

Well i do know that they've confirmed a vampire skill tree that is said to have a few spells specifically made for use while in vampire lord form. But i do know that they will have many, many new spells in the add-on, so i wouldnt worry too much about it.

There are spells that would fall into both categories and as far as i know they independent from the normal perk trees.I think you can use your charcter without any problems.

hopefully or i will have to use my altmer mage.
