What does special attack do on Pokemon mystery dungeon explorers of sky?

The Special Attack stat in Pokémon Mystery Dungeon: Explorers of Sky determines the power of a Pokémon's special attacks, such as Ember, Water Pulse, and Psychic. The higher a Pokémon's Special Attack stat, the more damage its special attacks will do.

Special Attack is also used to calculate the damage of non-damaging status-afflicting moves, such as Stun Spore and Thunder Wave. The higher a Pokémon's Special Attack stat, the more likely its status-afflicting moves will succeed.

In general, Pokémon with high Special Attack stats are good at using special attacks, while Pokémon with high Attack stats are good at using physical attacks. However, there are some Pokémon that have high stats in both Attack and Special Attack, making them versatile attackers.
