@ above: They're randomized. Much like Slash Blast+FA, Iron Arrow, and Pierce. It's not hard to figure out, just go to snails (Slimes are Lit Weak o_o) and spam CL a bunch of times. Record your max damage on one monster and on the second hit over 10 minutes or so. Divide the second number over the first and round to a reasonable number.
Ex If you hit a max of 24890 on your first hit and 18650 on your second hit,
18650/24890 = 74.92969...
and I'd assume it's a 75% multiplier across.
