So far as I can tell from the Wiki, you only get 20Hp for becoming Soulbound, but also get access to their abilities, obviously tying them together. I am just wondering if anyone has come through optimized a build for them? I've played a few versions of Kitsune but never tried to do anything on Dark Mode. It seems kind of interesting how each one is built, I did see a good looking build for Charmer Valkyrie, though haven't tried it personally.  Just wondering if anyone has some input they could give me for this.
