The Vampire tried to lay claim to my existence on this mortal coil, but I refused to fall prey to The Count and was able to vanquish this mighty and worthy foe.

Fantastic puzzle! Very cool spin on modifier cells. A pretty trippy break-in followed by a fun and challenging second half. In the end, closer to 4.5 stars for me. Highly recommended

Figuring out the break-in was very confusing. From there it stayed quite hard but you could sort of get the hang of it. I enjoyed working on this for the couple of hours it took.

What an awesome puzzle! Tricky and full of novelties (at least as far as I'm concerned). Thanks for this entertaining sudoku!
