I'm Using Sacrosanct
Our mods are NOT compatible. The patch simply allows you to use some of his abilities or powers. His feeding system cannot be active at the same time as mine - we use the same scripts.
The patch that I have made for my mod and Sacrosanct is an altered formlist and I have added a small script to the magic effect when you change into a Vampire Lord.
You will be able to use Sacrosanct's Vampire Lord perks and spells, but you CANNOT use any of his regular vampire progression scripts. His method of playing a Vampire is not compatible with BV, but with my patch you can use his spells etc.
You WILL have access to his Hemomancy spells and regular spells, but nothing else of regular vampirism can carry over.
You WILL be able to use his regular Vampire spells while in Vampire Lord form.
You need to change into a Vampire Lord once to have the regular Vampire spells added to you.
If you cure yourself of Vampirism, then wait one hour in game, all the regular Sacrosanct spells that my patch adds will be removed.
