why dont you just test it?
I did a quick test with the seeker missile, which shouldnt be bugged.
my weapon has 2,4% ls.
first without blood magic:
I leeched around 1200-1400life on a critical hit.
with bloodmagic(2,4%+1.5% = 3,9% ls):
around 2000-2200life on a critical hit.
the life on critical hit increased by around 70~%.
my ls increased by 70% aswell.
that means its scaled just like the ls from weapons. if blood magic wouldnt be scaled, my leech would be around 5500-6000life on a critical hit.
bare in mind that most numbers are rounded and I didnt made a test over a longer period of time, but the main thing is that the difference between scaled(20%) and unscaled ls should be huge. around factor 4-5x and not factor 1.7x just like in my quick test.
if anyone wants to do more tests especially in 1.0.5, feel free to do it.
I hope I made mistake somewhere becouse I would like to have 4x the leech I have now.
