8x40 and not even a sweat. I've been doing the same at th13 and gotten a 61 second attack on a max th13. It's hella fun!

Great idea with low level donated clone. Helps to clone them tiny mites. Lvl 6 clone or lower. Lvl6 has 34 clone cap and super yeti is 35

I don’t have the option to super yeti?  Can anyone advise why?
