Good to know. Thank you. I'll give it a try with Rem first and see how my damage is. My holy magic is actually pretty good, but I don't know how tanky Ark is yet. Though, I need to hone another Holy for Minwu. I'm guessing its savage mode is the reason I've heard of people doing it with physical teams.
One if the things I figured out using Rem aasb on ark is that Madeen will w-cast with it. So I used Holyja x3, glint, aasb, Madeen x2 while under the mag/mnd debuff, then back to Holyja for full power. The timing may be slightly different depending on how soon you get to his phase changed.
My second dd was Hope so this assumes that you have multiple copies of Madeen honed.
In other news Typhon is now sub 30.

I was a bit worried on this one because I don't have any ice heavy hitters (osb or aosb), not that there are a ton of them out there.
