Stat changes and critical hits

Moves, abilities and held items push a Pokemon's stats up and down mid battle. This is the part of Champions people get wrong most often, because the numbers are not percentages. They are stages, and a stage is worth different amounts depending on which stat it lands on.

Everything below is quoted from the game's own help text rather than worked out from play.

Stat Changes

A Pokémon’s stats can be boosted or lowered during a battle by effects from sources such as moves, Abilities, and held items. This is called a stat change.

Stat changes are measured in stages ranging from −6 to +6. The negative numbers indicate that a stat has been lowered, while the positive numbers indicate that it has been boosted. When a Pokémon is switched out of battle, these numbers will be reset to zero.

Stat changes can affect more than just a Pokémon’s stats, such as Attack and Defense. They can also affect a Pokémon’s evasiveness and accuracy.

When your Pokémon’s evasiveness is lowered, it will have a harder time evading moves. When its evasiveness is boosted, it becomes more likely that your opponents’ moves will miss. When your Pokémon’s accuracy is lowered, it will have a harder time hitting targets with its moves. When its accuracy is boosted, it is more likely to be able to hit targets with its moves.

The 7 things a stat change can hit

  • Attack
  • Defense
  • Sp. Atk
  • Sp. Def
  • Speed
  • evasiveness
  • accuracy

HP is not on that list. Nothing raises or lowers a Pokemon's maximum HP during a battle, which is also why stat alignment never touches it.

Critical Hits

A Pokémon’s moves have a 1-in-24 chance of landing as a critical hit. A critical hit will boost a move’s damage by 50%.

In addition, a critical hit will ignore certain stat changes and status changes.

When a Pokémon gains a Critical-Hit Ratio Boost, its odds of landing a critical hit will be increased. The Critical-Hit Ratio Boost status has stages that range from 0 to +3. The larger the number, the more likely the Pokémon will be to land a critical hit.
