Stats

Stats are a primary function of the game. Each stat is separated into different categories of Attack, Defense, Special Attack, Special Defense, Speed, and HP (Hit Points). Belly is also a stat exclusive to Pokémon Mystery Dungeon games. In PMU 5 and PMU 6, upon leveling up players would gain points that they could spend to increase stat values, but in PMU 7 stats became set off each Pokémon's base stat total for balancing purposes and accuracy to the games.

HP, Attack, Defense, Special Attack, Special Defense are normally defined by this formula:

$$Stat = (Base + 100) * (Level + 1) / 70 + 10$$

The current value of each of those stats for the active Pokémon can be seen in the team panel at the top of the game screen.

These six stats can have flat increases by items such as scarves, family items, and dusts and silks. Abilities (such as Flare Boost or Hustle) or other items such as Choice items or Pokémon-specific items will indirectly increase these stats; they will not be shown visually in the team panel but will be in effect all the same.

Attack
The Attack stat determines how much damage a Pokémon deals when using a physical move.

Defense
The Defense stat determines how much damage a Pokémon receives when it is hit with a physical move.

Special Attack
The Special Attack stat determines how much damage a Pokémon deals when using a special move.

Special Defense
The Special Defense stat determines how much damage a Pokémon receives when it is hit with a special move.

Speed
The Speed stat determines how quickly a Pokémon can recover from the cooldown of getting hit (known as "hitstun").

HP
Hit Points, or HP for short, determine how much damage a Pokémon can receive before fainting.

Evasion
Evasiveness affects the probability of dodging an opponent's move. A full list of Pokémon with access to evasion increases can be found here.

Accuracy
Accuracy affects the probability of hitting a target.

Movement Speed
Movement speed determines the quickness of a Pokémon's movement. Movement speed can only be increased on maps with None or No Penalty Morals.

Attack Speed
Attack speed determines the quickness of a Pokémon's attacks, on top of the base cooldown of a move. A full list of Pokémon with access to Attack Speed increases can be found here.

Belly
Belly is a stat that slowly depletes for the active Pokémon when walking or using items and moves, in dungeons only. The current amount of Belly can be seen in the 🇧🇹 menu. The base Belly size is 100, and it can be increased eating certain consumables while full. Belly will display three messages when it reaches 20, 10, and 0. Each member of the team has an individual Belly stat.

When Belly is fully depleted, Pokémon will lose 5 HP every five steps until the Belly is above 0. Going from a dungeon floor to a set floor will reset Belly to full, including resetting any size increases. Most edible items will fill Belly by some amount, as well as all seeds, berries and Gummis.

Temporary Stat Changes
Using certain moves, items, or certain Abilities coming into effect can increase or decrease a stat for the duration a Pokémon is on a map/dungeon floor. These modifications also won't be seen visually in the team panel. Temporary stat changes can be reverted by some moves, or by stepping on a Wonder Tile.

These stat changes can go up to 10 stages, rather than 6 like in the main series. How many stages a stat was affected by a change can be told by the message in the Battle Log.
