While trying for Spider using Illusion/Fire, I ended up getting Vampire as a fail.
I used diamond and wizard hoping for mismoth, but got vampire instead
I seem to can't escape Mistmoth at the moment. Had 4 or 5 of them while breeding for the Halloweens. Got them all in the end, three of them (Spider, Headless and Wraith) happened without even really trying for, Boo was quite easy, Zombie as well, Skeleton and Raven a pain, Witch I bought.
