Hi antrosapiens!
I'm the guy from the ML thread, who tried to help you to get Darkzgul.
I understood that this trick will not gives us 100% success, but I'm sure that it helps some extent, because (as you can see on the picture I attached) this is my fourth successfull legend breed in a row, after arch knight, thorder, and Goldfield.
So I'm still sorry for breeding you some rubbish monster instead of Darkzgul, but I can try it again, if you want, and if you take the risk.
