I could tell this is a magical puzzle just from how the grid looks like but man, did I struggle to find deductions during the mid solve. Lovely construction :)

Very nice! Incredible this solves with so few clues.
I just got my first 100% (yay!) which was an X-sums based puzzle too. id=0008T9 if you want to check it out.
