After a lot of trial and error, I believe I finally figured out how to add new spells to the vampire lord form. I found a number of people asking this question while researching myself with no real answer. I finally decided to try for myself and somehow managed to get them working each time after I solidified my process. Anyway, here's what you want to do. 1. Open CK and create a new spell. Create a new plugin if you are not using any mods that add new vampire lord abilities.* 2. Click on 'All' in the Object Window and type in 'dlc1vampirespellspowers'. A form list will appear in the right-hand window titled the same thing. 3. Open it up. This list is what Skyrim uses to modify the Favorites menu in the game to show the all the powers for the vampire lord. 4. Keeping the list open, find your newly created spell and just drag and drop it into the form list. The spell should appear in the list now. 5. Save your new plugin. Load it via any mod manager and open Skyrim. 6. Open up the console and type help "your spell name" and add it like any other spell. 7. Transform into the vampire lord and look in your powers menu. It should be in there now. Enjoy.** * Note: When creating the spell or ability, make absolutely sure the equip type is allocated to the left hand or for voice delivery. I highly recommend you do this to avoid any problems with the right hand spell. I believe the spell in the right hand is hard-coded for it. **Also once you add the spell, it might show up in your spell list when you are in normal form. I've had that happen with every spell I tried and I am not sure how to make it so the spell only stays with the vampire lord. I'm too lazy to figure it out right now. Anyway, I just wanted to share that bit of information to anyone still banging their heads on their bloody keyboard over this subject. Hope I opened a few doors, too.
