Structure
- game is again made up of multiple floors
- to win the game, the boss unit has to be slain once per each floor
- the boss unit is shown before starting the game and can be rerolled any number of times
- exit leading to the next floor is always located under the boss unit

Levels
- [Level] is no longer a unit property, it is now an always-visible game difficulty indication
- Level is increased by gaining enough [LP] (level points)
        - exploring a tile gives 1 LP
        - slaying a foe gives 10 LP
- Level indicates the number of combat slots given to your foe:
        - at Level 4, foes will own 4 combat slots (out of 16) and 12 will be yours
        - at Level 8, foes will own 8 combat slots (out of 16) and 8 will be yours
- total number of LP is equal to the value you'd get by exploring all floors and slaying all foes
- that number is evenly distributed for each Level

Mods
- added modifiers (mods): objects held by units that affect gameplay
- Soul mods are assigned to units automatically
- new mods can be attained through the bounty system
        - slaying a non-boss foe gives an option to select the reward mod

- mod effects mid-combat are indicated with text appearing over the affected slots
