I just got to this fight now. I've done most of the missions and bcs as pld/rdm. Decided to try the final fight with my usual trust combo of Arciela II, Shantotto II, Sylvie, Cherukuki, and Excenmille [S]. Clearly it did not work all that well
. I didn't do much prior research to the fight.
I do not have any of the trusts from the alter-ego campaigns, including what seems to be a favorite in Amchuchu. I can switch unities to get Apururu, but what other trust combinations should I consider? Should I go full support with 2x whm, Selt'heus, Ulmia, and Arciela II? Face CoD away from them? Stand further?
