Nana's main Artifice is her AP Increase to the backmost group, which increases the AP cost of all their moves by one - quite debilitating.
Her secondary Artifice is her Fortitude stacking, which builds up over the course of the battle and can unpleasantly extend the battle.
If you wish to bring a full wind team to the fight, bring no more than one backliner. Having more than one girl on the team with AP increase is far too debilitating. Or, as the teams below prove, let Nana stick her AP increase on a fodder who dies in a single hit.
As for her fortitude, multihit attacks can prove effective, or you can simply brawl it out for a little longer.
This boss is extremely outdated and has not appeared for an extended number of rotations. Hence, it will not be further updated.
1) How does that work, really?
Nurse Mei Fan's absorb stacking shenanigans can solo Nana much like Snow Maya, with the inclusion of a backline fodder, and if you are so inclined, a US stick in front of her, such as Ghost Patrol Ichie.
