First more-substantial update since I've been back: it's the weapon update.
Significant update to how weapons and enemies work;
Critical hits are now possible, and different weapons are rated C, B, A, or S depending on their chance to land a crit.
You can carry two weapons, and can swap between which is active in and out of combat.
Enemies have different attributes that interact with attack type and weapon type (positively or negatively)
Weapon attributes and details are visible within buttons on the sidebar
Weapons can have special effects
There are a few new story-related passages to find as well.
