Agility seems to be by far the most important stat in this game as it plays a major part in attack, defense, turn order, and ability to escape from battle. Having a high agility and critical hit rate in this game lets you relatively consistently one shot even powerful enemies like the new bear on the first floor without taking any damage. This was an issue in the previous iteration of this game where battles on later floors were very easy if you were properly set up, particularly since Hana on her own could consistently instantly crit your entire opponent team to death hitting multiple times (also very abusable) per turn. As an aside, bosses should probably get certain status immunity like fear and paralysis in this new iteration.
