Yeah any good shadowkin with mikage should out dps thor, but thor is better in a vacuum. Also, 2 cruel 6 merci should outdps 9 merci, especially in nightmare, where defence is higher
I'm a buff baby and I dance like a man. She a nice lady and she shakin her yams. It's nice to be done the Marius missions. My Marius is missing a lot of gear but he's in ss/lethal. Only 5k defense though since no defense ring or defense on banner/most of gear but at least he gets his own buff. Marius is goat for hydra I must say, he keeps up with toshiro with mikage due to max HP buff. Next rotation will hopefully he more friendly to magic affinity and I'll test damage again
Even with a wonky AI, Harima and Mikage are a formidable team, which I also employ on brutal though. Thor is a beast and will out perform most other dps one on one.
