Pokemon Champions battle conditions
All 66 field conditions the game tracks, with its own wording and its own numbers. Sun and Rain boost matching move damage by 50%, while Sandstorm and Snow instead give Rock and Ice a 50% defensive stat boost. Three of the four terrains add 30% to a type, and all of that is worth checking against whatever you remember from the mainline games.
Every description below is quoted from Pokemon Champions itself, so where it differs from your expectations the game is right. For the six status conditions that go on a Pokemon rather than the field, see status conditions.
