Stats

A stat in Mystery Dungeon is one of HP, Attack, Defense, Special Attack, and Special Defense. In addition, there are values for Accuracy, which affects the probability of hits for a Pokemon's attacks; Evasion, which affects the accuracy of opponents' attacks; and Movement Speed, which affects velocity and agility when moving.

In Mystery Dungeon, each Pokemon has a set of starting stats at level 1, and when a Pokemon levels up, each of its stats grows by a set amount. Attack, Defense, Special Attack, and Special Defense are 1 byte long, and HP is 2 bytes long. There are no individual values or effort values in this game.

Stat Stages

Each Pokemon has a set of stat stages that modify its stats when in a dungeon. They reset to 10 whenever it enters or leaves a dungeon floor. According to a Pokemon's stat stages, the Pokemon's stats and values can change in damage calculation or accuracy calculation.

Stat Multipliers

Some moves, such as Screech and Memento, modify stat multipliers instead of stat stages. Each Pokemon has a stat multiplier for Attack, Defense, Special Attack, and Special Defense, which each reset to 1 whenever the Pokemon enters a new floor.

Movement Speed

Movement Speed indicates the number of steps a Pokemon can move at once. For example, a Pokemon with a Movement Speed of 2 (double speed) can move up to two steps at once. To be more exact, Movement Speed indicates the number of consecutive turns that a Pokemon has, as long as the Pokemon spends all of them by just moving one space or standing still.

The game represents boosts and reductions to Movement Speed using ten bytes: five for boosts and five for reductions. These values reset to 0 whenever the Pokemon enters a new floor.

When a move that increases Movement Speed is used, a duration is set to (8-10)+1. The game does this by looking for a byte that equals 0 in order to replace it with the duration. (Duration means the number of turns that the effect lasts.) If all five durations are greater than zero, the effect fails.

When a move that reduces Movement Speed is used, a duration is set to (6-8)+1. A reduction in Movement Speed is treated as a status problem for the purpose of calculating its duration.

The Pokemon's Movement Speed is calculated at the beginning of its turn:

All Movement Speed durations are decreased by 1.
Movement Speed begins at 1 (normal speed).
Add the number of increases to Movement Speed (durations which are greater than 0).
Subtract the number of reductions to Movement Speed (durations which are greater than 0).
If the weather is snow, add 1 if the Pokemon's current type includes Ice.
If the Pokemon is Deoxys Speed Form, add 1.
If the Pokemon is paralyzed, subtract 1.

If Movement Speed is 0 or less, the Pokemon is "slowed down." This means that the Pokemon skips every other turn while its Movement Speed is 0, and it can move only one step during each of its turns.

A Pokemon's Movement Speed can't be greater than 4 or less than 0.

Movement Speed is not a stat and is thus not affected by effects that prevent reduction of stats or that restore stats to normal.
