Swine God more like pork roast...god

So I just almost had my first loss in a mission against the Swine God in what was also my first foray into a Champion level dungeon. I went in with my best Vestal/Plague Doctor/Hound Master/Crusader and left with only my Plague Doctor. A victory by inches. How the fuck do I do this shit? That's basically the easiest boss but he still fucked my shit up. Do I need certain team comps or something?
