If I'm not mistaken, Diablos attack is basically Demi which reduces the targets health by a percentage. My question is: Is the percentage of Diablo fixed at a number (ex. 1/4, 1/2, 3/4) or does it vary with enemies (ex. normal enemies 3/4 while bosses 1/4)? I knkow the max is 9999 overall.

Also, I may be mistaken, but I thought I have seen some very low level ememies be killed by the attack outright, instead of just getting reduced health.
