Using an ability like Adrenaline increases the Pokemon's attack for
three rounds. After those three rounds are up, it goes back to normal.
However, if you use Adrenaline with one Pokemon, and then Rally (also
increases atk) is used on that same Pokemon, these increases stack.
same for range and defense.
Those are temporary boosts mind you, and dissapear after the amount of
time listed. For things like Crack Shot which do not list a duration,
it basically means it only functions on the round you used it. All
stat raises due to abilities used in battle also end when the battle
does.
So that's what I was told by a friend of a friend who is an extreme gamer.
Basically as I understand it there are time durations on moves.
Also some moves can stack so using two different moves that raise attack can stack.
Negative stat changes CAN stack
unless you use a fancy dooda to get them reversed so on so forth, I stopped listening to him after he told me the first bit xD
Am I missing anything Kyron or was that all you wanted?
