Gameplay

The objective of the game is to reach the topmost floor of the tower. Outside of Rest Areas, each floor is randomly generated and the map is filled as the player explores it.

Each floor contains a portal to the next floor, and a number of randomly-generated treasure chests. It's also possible for Trish's Fountain to spawn in a floor.

As the player explores the tower, they unlock more party members by finding them. The party is limited to five characters, and changes in party lineup can only be performed at the base of the tower.

Shop

The shop will buy and sell items and equipment. The shop can be found at the base of the tower and Rest Areas. The shop's inventory won't update as the player progresses, rather each iteration of the shop has its own selection.

Warehouse

Defeat in battle does not result in a game over sequence, and instead the player will be sent to the base of the tower. However, they will have lost all their money, items, and equipment.

The Warehouse serves to mitigate that, allowing players to store and withdraw both items and money. The Warehouse can be found both on the tower's base as well as Rest Areas.

Refinery

The Refinery allows players to spend gemstones to permanently upgrade pieces of equipment. Each upgrade will increase the equipment's attack/defense stat by 10% and a bonus stat depending on the gemstone chosen.

Each piece of equipment can be refined up to ten times, but due to rounding errors it won't necessarily translate to a 100% upgrade.

Treasure Chests

Much like the floor layouts, the contents of treasure chests are also randomized.

Chest contents

Odds	Result
60%	Item
20%	Money
12%	Trap
5%	Full HP recovery
3%	Full SP recovery

Item Chests

Each floor has a maximum total of 25 possible items, divided in six categories. Each category has a different number of possible items in it. The game will first decide on a category and then choose an item inside of it. Each possible item inside of a category has an equal chance of being selected.

Item categories

Odds	No. of Items
15%	1
45%	8
10%	1
20%	7
9%	4
1%	4

Not all possible items correspond to a valid item ID. If such item is selected, the game will restart the process of selecting a category. This behavior is on purpose to make rare items even more rare, as invalid IDs are more prevalent in categories with rare items.

If the player is already carrying the maximum amount of the item chosen, the game will give the player either money, full HP recovery, or full SP recovery. Each of these three options will have equal odds among them.

Trapped Chests

Trap chest contents

Odds	Effect
25%	Damage equal to 5% of maximum HP to the entire party.
25%	Inflicts a random party member with Poison.
25%	Initiates a battle.
25%	Erases the player's map.

Trapped chests cannot occur on floors 1-10. If the game's random number generator selects the Trap category on those floors, it'll redo the calculation until it selects a different outcome.

The spell Liftoma and the item Core Shield will protect the player from a trapped chest. They won't prevent trapped chests from spawning, but will instead nullify the effects of the traps.

Money Chests

If a chest contains money, the amount is equal to the level of a random party member multiplied by 100.

Stats

The formulas used to calculate stats are different from Megami Ibunroku Persona, being more simplified.

Stat	Calculation
Weapon Attack	STR + Attack of current weapon
Weapon Hit	DEX + Hit of current weapon
Gun Attack	Attack of current gun + Attack of current bullet
Gun Hit	DEX + Hit of current gun
Defense	VIT + Defense of all current armor
Evasion	AGI + Evasion of all current armor

Escape	$80+({\text{Party's Average Level}}-{\text{Enemy's Average Level}})+{\frac {\text{Party's Average LUC}}{5}}-({\text{Moon Phase}}\times 3)$
