Hippocrates' persona begins with a support ability.

More specifically, Analysis 2. He's a great support character, but he'll be getting much more overconfident then he should on the 7th - aka, he'll even try and take on a Visceral Maya or two, despite being unable to inflict damage. If you want to knock him back down to his calm self, or otherwise be the person he supports, just let me know when you thread-proposition me.
