Thanks @Force Redux for this guide. I started Homecoming this week as a Ninja/Dark Miasma mastermind, and am having so much fun playing it. Around level 12 I started wondering if I should stick with Dark Miasma because my ninjas lack survivability, but based on your guide I am going to keep with it and see how things go in my 20s. Appreciate your work here!
Too bad Ninjas are not optimal compared to the other pets, but I am loving the theme anyway... It's cool running around with a squad of ninjas, using darkness to subdue our enemies. I feel like a shogun and I love it.
