@CJRULESHERRY- I'm almost certain monster level matters, and I know the number of torches matters, but I'm not sure about happiness. I think mainly there is a serious amount of luck involved- my son got all four ethereals without much problem, and he isn't too rigorous about leveling up his monsters or making them happy- he even managed to get a Jeeode with level 4 barely happy monsters and no torches! On the other hand I've gotten my monsters up to level 15, 100% happy and only in the last 24 hours have succeeded with Grumpyre & Reebro breeding after several weeks of trying, even with torches. So, just keep trying, and eventually it will happen.

Good Luck!
